Multiple-choice questions each have fout possible answers (a, b, c, d), one of which is correct. Assume that you guess the answers to three such questions, a. Uno the multiplication rule to find P(WCC), where denotes a correct answer and W denotes a wrong answat. P/WCC)-(Type an exact answer.) b. Beginning with WC, make a complete list at the different posalble arrampements of two correct answers and one wrong answer, then find the probability for each entry in the list P(WCC) - 500 above PCCW) - PICWC) (Type exact answers.) c. Based on the preceding results, what is the probability of gotting exactly two correct answers when three guesses are made? Typo an exact answer)
