Because many passengers who make reservations do not show​ up, airlines often overbook flights​ (sell more tickets than there are​ seats). A certain airplane holds 119 passengers. If the airline believes the rate of passenger​ no-shows is 9​% and sells 132 ​tickets, is it likely they will not have enough seats and someone will get​ bumped?
