Math Problem Statement
In February, a major airline had 77.8% 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. 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? b. Discuss how realistic it is to assume that the on-time arrivals of the different flights are independent.
