Multiple choice question each have four possible answers (a, b, c, d), one of which is correct. Assume that you guess the answer to 3 questions. a) Use the multiplication rule to find P(WWC), where C denotes a correct answer and W denotes a wrong answer. b) Beginning with WWC, make a complete list of different possible arrangements of one correct answer and two wrong answers, then find the probablity for each entry in the list: P(WWC) - see above P(WCW) = ____ P(CWW) = ____ c) Based on the preceding results, what is the probability of getting exactly one correct answer when 3 guesses are made?

Q:
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(WWC), where C denotes a correct answer and W a wrong answer. P(WWC)= ____ b. Beginning with WWC, make a complete list of the diff. possible arrangements of one correct answer and two incorrect answers, then find the probability for each entry. P(WCW)= _____ P(CWW)= _____ c. What is the probability of getting exactly one correct answer when three quesses are made?
