A peculiar die has the following properties: on any roll the probability of rolling either a 4, a 5, or a 3 is 12, just as it is with an ordinary die. Moreover, the probability of rolling either a 3, a 2, or a 1 is again 12. However, the probability of rolling a 3 is 14, not 16 as one would expect of an ordinary fair die. From what you know about this peculiar die, compute the following. a....

A game involves rolling a fair six-sided die. If the number obtained on the die is a multiple of three, the player wins an amount equal to the number on the die times $20. If the number is not a multiple of three, the player gets nothing. How will you model the simulation for the roll of a die? A. Use the numbers 1–20 to represent the numbers rolled when a player wins. B. Use the numbers 1–6 to represent...
