Q:

Air-USA has a policy of booking as many as 24 persons on an airplane that can seat only 22. (Past studies have revealed that only 86% of the booked passengers actually arrive for the flight.) Find the probability that if Air-USA books 24 persons, not enough seats will be available. prob = Is this probability low enough so that overbooking problems will be unusual? (Define unusual as having probability 5% or less) yes, it is low enough no, it is not low enough What about defining unusual as 10% or less? no, it is not low enough yes, it is low enough

Accepted Solution

A:
Answer:B. no, it is not low enoughA. no, it is not low enoughStep-by-step explanation:Given that Air-USA has a policy of booking as many as 24 persons on an airplane that can seat only 22.Prob for  a random person booked arrive for flight = 0.86No of persons who books and arrive for flight, X is binomial, since there are two outcomes and each person is independent of the other The probability that if Air-USA books 24 persons, not enough seats will be available= P(X=23)+P(x=24)= 0.1315B. no, it is not low enough-------------------------------The prob we got is >10% alsoA. no, it is not low enough
