A friend has approached you asking for help estimating the winning odds on a heavily modified variation of a popular dice game. His version of the game works as follows:

• The player rolls 3 dice, each die has 6 sides

• If the total rolled is 3,4,5,16,17 or 18 the player loses

• If the total rolled is 7 or 11 the player wins

• If any other number is rolled, the player rolls again

• Rerolls work the same way as the initial roll, except that if the player rolls the same number as their

first roll they win. For example if the player rolls 15-13-6-15 they would win

You decide to use a Monte Carlo simulation to estimate the odds.

When preparing your analysis you should assume the following:

• No more than 50 rolls are required to achieve a result

• 5000 outcomes are required to prepare your Monte Carlo.

For simplicity, you should use a Data Table to run your Monte Carlo.

Questions

1. What is the probability of the player winning the game?

2. What is the average number of rolls per game?

3. Your friend decides to include the numbers 8 and 9 as a losing number for only the initial roll, what is the

new probability of the player winning the game?

Turn in no more than a page in which you clearly lay out your calculations, to the best extent possible.

Here is the model that we worked on in class, if that’s helpful to you.
