PROBABILITY OF AT LEAST ONE Let A = the event of getting at least 1 malfunc- tioning iPhone when 3 iPhones are ran- domly selected with replacement from a batch. Based on data from Statista, the malfunction rate is 7.5%. Which of the following are correct? a. P(A) = (0.925)(0.925)(0.925) = 0.791 b. P(A) = 1 - (0.925)(0.925)(0.925) = 0.209 c. P(A) = (0.075)(0.075)(0.075) = 0.000422
