Consider a segment of an electrical circuit with three relays connected in parallel. Current flows through the circuit if at least one relay is functioning when the "system" is turned on. Suppose the relays function independently and assume their lifetimes are distributed exponentially with a mean of 30 days. (a) What is the probability a relay lasts longer than 60 days? (b) What is the probability that the “system" will last longer that 60 days.
