Air-USA has a policy of booking as many as 19 persons on an airplane that can seat only 17. (Past studies have revealed that only 83% of the booked passengers actually arrive for the flight.) What is the expected number of passengers to arrive for the flight? Expected number of passengers - (please round to two decimal places) Find the probability that if Air-USA books 19 persons, not enough seats will be available. (please round to four decimal places) prob = Is this probability low enough so that overbooking is not a real concern for passengers if you define unusual as 5% or less? Oyes, it is low enough not to be a concern O no, it is not low enough to not be a concern What about defining unusual as 10% or less? O yes, it is low enough not to be a concern po it is not low enough to not be a concern
