Question 416405: Each question of a five-question multiple choice exam has four possible answers. Whitney picks an answer at random for each question. Find the probability that she selects the correct answer on only the second and third question. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Each question of a five-question multiple choice exam has four possible answers. Whitney picks an answer at random for each question. Find the probability that she selects the correct answer on only the second and third question.
---------
P(correct) = 1/4
P(wrong) = 3/4
-------------------------
P(WRRW) = (3/4)^2(1/4)^2 = 9/16^2
