ased on long experience, an airline found that about 4% of the people making reservations on a flight from Miami to Denver do not show up for the flight. Suppose the airline overbooks this flight by selling 265 ticket reservations for an airplane with only 255 seats. (a) What is the probability that a person holding a reservation will show up for the flight?(b) Let n = 265 represent the number of ticket reservations. Let r represent the number of people with reservations who show up for the flight.
