Consider purchasing a system of audio components consisting of a receiver, a pair of speakers, and a cd player. let a1 be the event that the receiver functions properly throughout the warranty period, a2 be the event that the speakers function properly throughout the warranty period, and a3 be the event that the cd player functions properly throughout the warranty period. suppose that these events are (mutually) independent with p(a1) = 0.94, p(a2) = 0.92, and p(a3) = 0.90. (round your answers to four decimal places.)
