Multiple-choice questions each have five 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 rule to find ​P(CWC​), where C denotes a correct answer and W denotes a wrong answer. b. Beginning with CWC​ ,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(CWC​)= ​P(WCC​)= ​P(CCW)=   c. Based on the preceding​ results, what is the probability of getting exactly two correct answers when three guesses are​ made?
