Assuming that engine failures are independent of each other, what is the probability that on a certain transcontinental flight, a six-engine plane will experience exactly one engine failure?
The probability that an airplane engine will fail in a transcontinental flight is 0.001.
More than two engine failures?

Explanation:
Lets say engine 1 fails and engines 2-6 work properly
the probability is
now the cases are only engine 1 fails or only engine 2 fails and so on, we have 6 cases that are equally likely
so the probability is multiplied by 6
we get
