Because all airline passengers do not show up for their reserved sear an airline sells n=125 tickets for a flight that holds only 120 passengers. The probability that a passenger does not show up is 0.10 assume that the passengers behave independently.
Airlines sometimes overbook flights. Suppose that for a plane with 50 seats,55 passengers have tickets. Define the random variable Yas the number of ticketed passengers who actually show up for the flight. The probability mass function of Y appears in the accompanying table. y 45 46 47 48 49 50 51 52 53 54 55 p( y) .05 .10 .12 .14 .25 .17 .06 .05 .03 .02 .01 a. What is the probability that the flight will accommodate all ticketed passengers who show up? b. What is the probability that not all ticketed passengers who show up can be accommodated? c. If you are the first person on the standby list (which means you will be the first one to get on the plane if there are any seats available after all ticketed passengers have been accommodated), what is the probability that you will be able to take the flight? What is this probability if you are the third person on the standby list?
