Hi everyone,

I have been having trouble with this problem in my Statistics class. 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 carefully.

I think I have figured it out but I need some reassurance. The answers I got were:

a) .04

b) 0

c) .02

Is this correct or am I missing something. I would greatly appreciate the help! Thanks in advance!
