# Hospitals typically require backup generators to provide electricity in the event of a power outage assume the emergency back up generators feel 22% of the times when they are needed. The hospital has to back up generators so that the power is available if one of them fails during the power outage.  Find the probability to four decimal places that both generators fell during a power outage.
