multiple-choice questions each have four possible answers left parenthesis a comma b comma c comma d right parenthesis, 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)minussee above p(wcc)equals? 0.046875 p(ccw)equals? 0.046875 (type exact answers.)
c. based on the preceding results, what is the probability of getting exactly two correct answers when three guesses aremade?
