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? (b) Neither will fail? (c) One or the other will fail? Show all steps.

(a) (0.02)^2 = 0.0004
(b) (0.98)^2 = 0.9604
(c) (0.02)(0.98) + (0.98)(0.02) = 0.0392
Note that the sum is 1.0000
