Multiple-choice questions each have five possible answers (a, b, c, d, e), one of which is correct. Assume that you guess the answers to three such questions. a. Use the multiplication rule to find P(WCC), where C denotes correct answer and W denotes a wrong answer. P(WCC) = 4 125 (Type an exact answer.) C b. Beginning with WCC, make a complete list of the different possible arrangements of two correct answers and one wrong answer, then find the probability for each entry in the list. P(WCC)- see above P(CCW) = P(CWC) = (Type exact answers.)
