# Option #1: Bunco

For this Critical Thinking assignment, you will apply concepts from probability theory to real-world scenarios.

Bunco is a group dice game that requires no skill. The objective of the game is to accumulate points by rolling certain combinations. The game is played with three dice, but we will consider a simpler version involving only two dice.

How do you play two dice Bunco?

• There are six rounds, one for each of the possible outcomes in a die, namely the numbers one through six.
• Going clockwise, players take turns rolling two dice trying to score points. Points are usually awarded as such: 21 points if both dice match the current round number (a “Bunco”); five points are awarded if both dice match each other, but do not match the current round number (a “Mini Bunco”). Finally, one point is awarded for a single die matching the current round number.
• If points are scored, the player gets to roll again, continuing to add to their score. If no points are awarded, the player’s turn ends and the dice are passed to the next player.
• At the end of the game, the winners get prizes for accomplishments such as the highest score, the lowest score, or the most buncos.

Part I: Complete the following steps assuming the round number is 6:

1. What is the probability that the player rolls two distinct numbers different than six or rolls exactly one six (no points or one point)?
2. What is the probability that the player rolls two of the same number but no six, i.e., two 1s, or two 2s, and so on (five points Mini Bunco)?
3. What is the probability that the player rolls two 6s (21 points Bunco)?
4. Compute the total of the probabilities found in the three previous questions.
5. If the player wins a dollar for every point, he/she gets and losses three dollars for getting no points, what are the expected winnings or losses on each roll?

Part II: Based on your work in Part I, discuss the following:

1. Describe the sample space when rolling two dice once. How can identifying all the elements of the sample space help you answer the questions in Part I?
2. Determine if “rolling two different numbers different than six” or “rolling exactly one six” are mutually exclusive events. Justify your answer. Explain how this information can help you answer question one, Part I.
3. Describe the relationship between odds and probability. Explain how you can use the result in question three, Part I to find the odds of getting a Bunco in a single roll.
4. What does the result found in question four, Part I imply about these events? Explain how you have used the answers to questions one and two, Part I to get the answer to question three, Part I.
5. Interpret the answer to question five, Part I.
6. Discuss the advantages of understanding probabilities when playing dice games.
7. Think of another scenario where probabilities can be used. Discuss the advantages of using probabilities in the context of the scenario you created.

Requirements:

You must submit two files for this assignment. The first file should contain the computations, graphs, diagrams, etc., associated with the questions in Part I. This file may be formatted as a numbered list of answers. Unless stated in the problem, a narrative discussion is not required, but you must provide enough information to show how you arrived at the answer.

The second file should be a 2-3-page narrative paper, written in APA format, associated with the situation described in Part II. Specific requirements for the paper are provided below:

1. Your paper should be 2-3 pages in length (not counting the title page and references page) and should cite and integrate at least two credible outside sources. The CSU-Global Library is a great place to find resources. Your textbook is a credible resource.
2. Include a title page, introduction, body, conclusion, and a reference page.
1. The introduction should describe or summarize the topic or problem. It might discuss the general applications of the topic or it might introduce the unique terminology associated with the topic.
2. The body of your paper should address the questions posed in the problem. Explain how you approached and answered the question or solved the problem, and, for each question, show all steps involved. Be sure this is in paragraph format, not numbered answers like a homework assignment.
• The conclusion should summarize your thoughts about what you have determined from your analysis in completing the assignment. Nothing new should be introduced in the conclusion that was not previously discussed in the body paragraphs.
1. Include any tables of data or calculations, calculated values, and/or graphs referenced in the paper. (Note: The minimum required length excludes any tables, graphs, etc.)
2. Document formatting, citations, and style should conform to the CSU-Global Guide to Writing and APA Requirements(Links to an external site.). A short summary containing much that you need to know about paper formatting, citations, and references is contained in the Template Paper (Links to an external site.). If you need assistance with your writing style or you need writing tips or tutorials, visit the CSU-Global Writing Center (Links to an external site.).
