In​ February, a major airline had 77.6 of their flights arrive on time. Assume that the event that a given flight arrives on time is independent of the event that another flight arrives on time.

A writer plans to take four separate flights for her publisher next month. Assuming the airline has the same​ on-time performance as in​ February, what is the probability that all four flights arrive on time?
