Question: Suppose the BART train system in California has 5 backup generators in use in the North Bay Area for when PG&E cuts power. Each one of them has a probability of 0.99 when functioning turned on. You may assume independence of the generators.

A. What is the probability that none of the generators will work?

B. If we require the use of 2 generators to provide enough power for the day, what is the probability we will not be able to provide that power?
