Multiple-choice questions each have four possible answers (a, b. c, d), one of which is correct, Assume that you guess the answers to three such questions. a. Use the multiplication nule to find P(WCC), where C denates a correct answer and W denotes a wrong answer. P(WCC) =Type an exact answer.) b. Beginning with WCC., make a complete list of the different possible arrangements of two correct answers and one wrong answer, then find the probabity for each entry in the list. P(WCC) - see above P(CCW) = P(CWC) = (Type exact answers.) c. Based on the preceding results, what is the probability of geotting exactly two correct answers when three guesses are made?
