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 - [0.9604+0.0004] = 0.03920
-------------------------------------------
