Suppose a multiple-choice test has 12 questions, each with four possible answers (A, B, C, D). Only one answer per question is correct. A student who did not prepare for the test plans to simply guess the answers. a. Find the probability that the student guesses all the answers incorrectly (that is, all wrong). b. Find the probability that the student guesses 3 of 12 answers correctly (thus scoring 25%).
