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) both will fail?;;(0.02)^2
---------------------------------
(b)neither will fail?:: (0.98)^2
--------
(c) one of the other will fail?::: 1-[0.02^2+0.98^2]
