A certain airplane has two independent alternators to provide electrical power. The probability that a given alternator will fail on a 1-hour flight is .02. What is the probability that
(a) P(both will fail) = 0.02^2 = 0.0004
(b) P(Neither will fail) = (0.98)^2 = 0.9604
(c) P(One or the other will fail) = 1 - (0.0004+0.9604) = 1-0.9808 = 0.0392
