BINOMIAL DISTRIBUTION: Suppose you are given a 3 question multiple- choice test. Each question has 4responses and only one is correct. Suppose you want to find the probability that you can just guess at the answers and get 2 questions right. (Teachers do this all the time when they make up a multiple-choice test to see if students can still pass without studying. In most cases the students can't.) To help with the ide that you are going to guess, suppose the test is in Martian. What is the probability of getting 2 questions right? *
