Multiple-choice questions each have five possible answers

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 (CCW), where C denotes a correct answer and W a wrong answer.
P( CCW)= ____

Beginning with CCW, make a complete list of the diff. possible arrangements of Two correct answer and one wrong answers, then find the probability for each entry.
P(CCW)= _____
P(WCC)= _____
c. What is the probability of getting exactly one correct answer when three quesses are made?
