Problem 7. (6 points) A multiple-choice test is constructed so that each problem has five possible answers, exactly one of which is correct. Joe Bozo always guesses on multiple choice tests, so the probability he gets any particular problem correct is 1/5 -0.2. (a) Suppose Joe takes a test with twelve questions. What is the probability he will get exactly four of the problems correct?
