Air-USA has a policy of booking as many as 21 persons on an
airplane that can seat only 19. (Past studies have revealed that
only 89% of the booked passengers actually arrive for the
flight.)
Find the probability that if Air-USA books 21 persons, not enough
seats will be available.
P(P(not enough seats))
Is this probability low enough so that overbooking is not a real
concern for passengers if you define unusual as 5% or less?
What about defining unusual as 10% or less?
