Question 383413: A certain airplane has two alternators to provide electrical power. The probability that a given alternator will fail on a 1-hour flight is .02.
Let P(A) be for the first alternator and P(B) be for the second. Therefore,
P(A) = .02
P(B) = .02
a. What is the probability that both will fail?
b. What is the probability that neither will fail?
c. One or the other will fail?

You can put this solution on YOUR website!
P(A) = .02
P(B) = .02
a. What is the probability that both will fail?::0.02^2
-------------------------------
b. What is the probability that neither will fail?::0.98^2
-------------------------------
c. One or the other will fail?::: 1-[0.02^2+0.98^2]
