HOMEWORK
Design an experiment to determine the probability of passing a six-question
multiple choice test if you guess all the answers. Each question has four
answers, and one answer is correct in each case.
How many simulations would seem reasonable?
What is the experimental probability of getting at least 50% on the test?
