In answering a multiple-choice question, a student either knows the correct answer or guesses. Assume the (prior) probability that a student knows the correct answer is p = 0.5. Also assume that a student who guesses at the answer will be correct with probability 1/m, where m is the number of multiple-choice alternatives. If you want to ensure that the probability that a student knew the answer to a question given that he answered it correctly is at least 0. 75, how large must m be?
