Item 1
Question 1
You randomly guess the answers to four true-false questions.
a. Which simulation can you use to model the answers?
Roll four number cubes. Let the number 1 represent a correct answer and the number 2 represent an incorrect answer.
Roll a number cube and let the numbers 1 through 4 represent the number of questions you guess correctly. Run 40 trials.
Roll two number cubes. Let one number cube represent a correct answer and the other number cube represent an incorrect answer. Run 40 trials.
Roll four number cubes. Let an odd number represent a correct answer and an even number represent an incorrect answer. Run 40 trials.
Question 2
b. Use the simulation results to find the experimental probability that you answer all four questions correctly.
