Airlines usually overbook for a flight (sell more tickets than the numbers of available seats).

Airlines usually overbook for a flight (sell more tickets than the numbers of available seats). They do this because they know from past experience that only 90% of ticketed passengers actually show up for the flight. a). A plane has 8 seats. If the airline sells 10 tickets for this flight, what is the probability that the flight will be overbooked? b). A plane has 300 seats. If the airline sells 320 tickets for a flight, what is the probability that the flight will be overbooked (Use the normal approximation)
