Describe Binomial Probability Distribution.B. Suppose you are given a 3 question multiple-choice test. Each question has 4 responses andonly one is correct. Suppose you want to find the probability that you can just guess at theanswers 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.) Tohelp with the idea that you are going to guess, suppose the test is in Martian.a.) What is the random variable?b.) Is this a binomial experiment?c.) What is the probability of getting 2 questions right?d.) What is the probability of getting zero right, one right, and all three right?
