Paul has just been given a 10-question multiple choice test in his Statistics class. Each question has five answers only, only one of those answers is correct. Since Paul has not attended class recently, he does not know any of the answers. Assume that Paul guesses randomly on all ten questions.

a. Use the binomial distribution equation to find the probability that he will answer all 10-questions correctly.

b. If he must get AT LEAST 7 question correct to pass the test, what is the probability that he will pass the test.

c. Find the probability that he will answer none of the question
