Probability of a Small Straight in Yahtzee in One Roll

Yahtzee is a dice game that uses five standard six-sided dice. On each turn, players are given three rolls to obtain several different objectives. After each roll, a player may decide which of the dice (if any) are to be retained and which are to be rerolled. The objectives include a variety of different kinds of combinations, many of which are taken from poker. Every different kind of combination is worth a different amount of points. Two of the types of combinations that players must roll are called straights: a small straight and a large straight. Like poker straights, these combinations consist of sequential dice. Small straights employ four of the five dice and large straights use all five dice. Due to the randomness of the rolling of dice, the probability can be used to analyze how likely it is to roll a small straight in a single roll. Assumptions We assume that the dice used are fair and independent of one another. Thus there is a uniform sample space consisting of all possible rolls of the five dice. Although Yahtzee allows three rolls, for simplicity we will only consider the case that we obtain a small straight in a single roll. Sample Space Since we are working with a uniform sample space, the calculation of our probability becomes a calculation of a couple of counting problems. The probability of a small straight is the number of ways to roll a small straight, divided by the number of outcomes in the sample space. It is very easy to count the number of outcomes in the sample space. We are rolling five dice and each of these dice can have one of six different outcomes. A basic application of the multiplication principle tells us that the sample space has 6 x 6 x 6 x 6 x 6 65 7776 outcomes. This number will be the denominator of the fractions that we use for our probability. Number of Straights Next, we need to know how many ways there are to roll a small straight. This is more difficult than calculating the size of the sample space. We begin by counting how many straights are possible. A small straight is easier to roll than a large straight, however, it is harder to count the number of ways of rolling this type of straight. A small straight consists of exactly four sequential numbers. Since there are six different faces of the die, there are three possible small straights: {1, 2, 3, 4}, {2, 3, 4, 5} and {3, 4, 5, 6}. The difficulty arises in considering what happens with the fifth die. In each of these cases, the fifth die must be a number that does not create a large straight. For example, if the first four dice were 1, 2, 3, and 4, the fifth die could be anything other than 5. If the fifth die was a 5, then we would have a large straight rather than a small straight. This means that there are five possible rolls that give the small straight {1, 2, 3, 4}, five possible rolls that give the small straight {3, 4, 5, 6} and four possible rolls that give the small straight {2, 3, 4, 5}. This last case is different because rolling a 1 or a 6 for the fifth die will change {2, 3, 4, 5} into a large straight. This means that there are 14 different ways that five dice can give us a small straight. Now we determine the different number of ways to roll a particular set of dice that give us a straight. Since we only need to know how many ways there are to do this, we can use some basic counting techniques. Of the 14 distinct ways to obtain small straights, only two of these {1,2,3,4,6} and {1,3,4,5,6} are sets with distinct elements. There are 5! 120 ways to roll each for a total of 2 x 5! 240 small straights. The other 12 ways to have a small straight are technically multisets as they all contain a repeated element. For one particular multiset, such as [1,1,2,3,4], we will count the number od different ways to roll this. Think of the dice as five positions in a row: There are C(5,2) 10 ways to position the two repeated elements among the five dice.There are 3! 6 ways to arrange the three distinct elements. By the multiplication principle, there are 6 x 10 60 different ways to roll the dice 1,1,2,3,4 in a single roll. There are 60 ways to roll one such small straight with this particular fifth die. Since there are 12 multisets giving a different listing of five dice, there are 60 x 12 720 ways to roll a small straight in which two dice match. In total there are 2 x 5! 12 x 60 960 ways to roll a small straight. Probability Now the probability of rolling a small straight is a simple division calculation. Since there are 960 different ways to roll a small straight in a single roll and there are 7776 rolls of five dice possible, the probability of rolling a small straight is 960/7776, which is close to 1/8 and 12.3%. Of course, it is more likely than not that the first roll is not a straight. If this is the case, then we are allowed two more rolls making a small straight much more likely. The probability of this is much more complicated to determine because of all of the possible situations that would need to be considered.

Part IV Condensed Version Free Essays

As an overview, Cleanthes is described as a philosopher that has a calm disposition. Demea is the one more concerned in the cause of religion. Philo is the arbiter or mediator between the ideas presented by Cleanthes and Demea. We will write a custom essay sample on Part IV: Condensed Version or any similar topic only for you Order Now Cleanthes was wondering why Demea was insisting that the Deity had no resemblance to humans in terms of human mind and understanding. For Cleanthes, the Deity has powers that humans cannot comprehend, for that is its nature––unexplainable. Though incomprehensible, Cleanthes recognized the Deity as a supreme being. Cleanthes also questioned Demea what was the difference of those who believed in the Deity and those who were Sceptics or Atheists. Atheists believed that the first cause of all was an unknown being. Atheists do not recognize the existence of a Deity. Atheists have boldness. Not only they had rejected the production by a mind, they also pretend to assign intelligible cause. Demea replied and commented that Cleanthes had presented his thoughts concerning the Deity with criticism instead of reasoning. Demea presented the comparison between the Deity and humans since Cleanthes said that the Deity is similar to the way humans think and understand. A human mind is filled with ideas, feelings, passions, and different faculties. And the human mind varies from one person to another. Though they vary from one another, the ideas they presented have form or order. The Deity has a perfect nature. He is able to see into the past, into the present, and into the future. Also, unlike the human mind that can change from one instance to another, the Deity has a fixed and firmed decision. The presence of the Deity is felt by those who believe in it. He is present everywhere, unlike humans who can only exist in one place at a certain point in time. Cleanthes again commented based on Demea’s words. With the way Demea explained, Cleanthes said that those â€Å"who maintain the perfect simplicity of the Supreme Being† were considered Atheists, yet they were unaware of it. For if we recognized the existence of the Deity, and since we know that his characteristics are incomprehensible, humans must give the Deity the respect he deserves. As humans, it is but natural to give due respect to the Deity. However, humans who do not give due respect to the Deity are diverging to the accustomed way of the Deity’s nature. It all bois down to human mind and the way it perceives things. Those who do not respect the Deity have restricted their minds to think of ways to give glory to the Deity. A mind that thinks with simplicity cannot think of creative reasoning and normally inclined to what is common, or to something that has no uniqueness at all. Demea chose to believe in the â€Å"perfect simplicity† of the Deity. The way we defined simplicity does not describe the true nature of the Deity, for the Deity’s mind definitely does not think simply. Same with humans, the Deity’s way of thinking is complicated yet creative. Philo, upon hearing the exchange of ideas between Cleanthes and Demea, argued that in order to know â€Å"the cause of that Being whom you suppose the Author of Nature,† they could judge the matter by reason or by experience. With reasoning we are able to explain the cause of every idea we thought of. We explain things based on reasoning that involves a whole lot of mind thinking. With experience we are able to explain the cause based on what we had experienced or what others had experienced. And because experience differs from one person to another, no two individual can think exactly alike. In reasoning, the mental world and the material world both need a cause. In experience, the material world is much easier to comprehend than the mental world because the material world is tangible unlike the mental world or the world of ideas. Philo continued to argue that in order to understand the cause of the Author of Nature why not consider focusing on the present material world. What is beyond the material world is vague and unknown. It is like saying to be contended on what we presently know about the Deity or God and do not worry ourselves on what is incomprehensible to us. The most important is that we know that there is a God. Philo added that some philosophers were ignorant and yet they disguised to know explanation to some matters. Such philosophers were called Peripatetics they would reason out and yet they were not really knowledgeable of the matter. They took advantage of those who were unaware of the matter. The matter on having an order in the ideas of the Supreme Being was an example. Some philosophers explained that having order is just one of the natures of the Deity. Cleanthes commented that Philo’s arguments were easy to answer. Cleanthes gave an example that if he were assigned cause for an event, would there be a problem if he could not tell the cause of that cause? For Cleanthes, knowing the Deity is the most important. He had stopped his inquiries and settled on the fact that there is a Deity. He did not push to knowing the cause or the order of the ideas of the Deity. For him, the existence of the Deity is what is more important. Believing on this fact is already enough. He would not busy himself on discovering what else should be known about the Deity. However, Cleanthes also said that those who would want to know what is beyond the existence of a Deity may do so. Philo said that he pretended not to be like Cleanthes who stopped thinking what lies ahead or what is beyond the existence of the Deity. Philo also pretended not to be like those who go and explore beyond to inquiry more of the existence of the Deity. Philo said he should have not attempted to expound on his arguments. Philo stressed that naturalists, with regard to the matter about the Deity, normally explain their ideas by giving out general causes. How to cite Part IV: Condensed Version, Papers

Managing Culturally Diverse Workplaces Essay Example | Topics and Well Written Essays - 1250 words

Managing Culturally Diverse Workplaces - Essay Example Such a tight private schedule may, of course, have consequences for working life. Another aspect of privacy is that Scandinavians are not very extrovert. These unique features of Bosnian employee sallow to say that Ado and his wife Alen require speicla programs and attention of supervisor (Barham and Conway 1998). The main problems faced by people in Bosnia are unstable political situation and cultural diversity (racism) caused by national differences between Bosnia and Herzegovina. Nationalism and civil war state cause people to be suspicious and distrustful. Bosnia suffers from economic crisis and high inflation rates, social and political instability, poverty and low quality of healthcare services. Coming to Brisbane, it is difficult for Ado and his family to adapt to new environment and overcome cultural shock (Brislin, 1993). Bosnian manager is not supposed to publicly reveal his or her feelings - and if he or she does, it should be separated from 'objective' and 'rational' decisions (Brislin, 1993). This means, among other things, that Bosnians are commonly described as 'serious. Bosnian businesspeople describe themselves, among other characteristics, as serious; sensible and silent. The Bosnian disposition to reasonableness, tolerance compromise and modesty also has a negative aspect in that some would argue that a person can discern forces that might work against initiative, risk-taking and, in extension, keep down entrepreneurialism (Bartlett and Ghoshal 1999). 2. The main strategies which would help Ado and his family to overcome cultural shock are cross cultural participation and a special plan for career opportunities, attention to need of the family and relocation assistance. A few minutes of "small talk" can often reduce the stress. Effective administrators know when to slow the pace and talk about nonthreatening subjects. However, not even the most tactful administrators always succeed in establishing trust. A small number of minority approach managers and supervisors in ways that are outright defensive--they use profanity and behave indiscreetly. Such defense mechanisms do not usually reflect faulty personalities. Rather, protection of the ego is normal; but a disproportionate use of defenses indicates a lack of security. Culturally different workers, particularly ethnic minorities, seek to maintain their psychological balance during times of stress in several ways, such as by rationalizations, reaction formation, overcompensation, o r projection. People who believe they are members of an underclass or out-group often develop rigid, persistent, and chronic ego-protection devices (Brake et al 1995). The major determining factor is the quality of interaction among people. The first step in establishing rapport with minority workers is to help them relax. To do so, the administrator must be relaxed. A special attention should be given to accommodation and food of Ado and his family. A company can advise Ado where to buy special food and how to behave in new environment. It is important to familiarize Ado with new cultural traditions and organizational culture, value
