Q. 3When rolling five dice, the possible totals range from 5 (5 ones) to 30 (5 sixes). Describe how you might use a random number generator to construct a probability distribution for the outcomes of rolling five dice.
Q. 4In a simple game of chance, the numbers 1, 2, 3, 4, and 5 are each written on a piece of paper and placed into a hat. A player draws a piece at random, and if the player draws the 3, the player wins. Describe how you would use simulation to estimate the probability of winning the game 2 or more times out of three plays. (Assume all numbers are returned to the hat prior to each round.)

Q. 6Which of the following is true of computer simulations?
a. The results are only as good as the instructions and models provided to the computer.
b. Simulations are usually much more time-consuming and costly than experiments or studies.
c. Since simulations are performed by computer, human error is eliminated, and thus the simulation results describe the modeled system exactly.
d. a and c only
