Question

(1 point) A certain airline has 166 seats available for a flight from YYC (Calgary International Airport) to LAX (Los Angeles International Airport). Because people with reservations do not show up for their flight 10% of the time, the airline always overbooks this flight. That is, there are more passengers that have tickets on the flight than there are seats. Suppose the airline has 181 passengers booked for 166 seats. Assume one person showing up for the flight does not effect others who may, or may not, show up for this flight.

(c) What is the probability that a passenger with a flight reservation will not make it to LAX due to overbooking? Use four decimals in your answer.

Explanation / Answer

C.==>> probability of showing up p=1-0.10=0.90

probability that a passenger with a flight reservation will not make it to LAX due to overbooking=P(at least 166 peole of showing up)=P(X>=166) = 1- P(X<=165) = 1-0.7338=0.2662

======Use Excel function ''=BINOMDIST(165,181,0.9,TRUE)'' to find probability.

Hope this will be helpful. thanks and God Bless You:)
