An airline has a policy of booking as many as 17 persons on an airplane that can seat only 16. (Past studies have shown that only 89% of the booked passengers actually arrive for a flight.) Find the probability that if an airline books 17 persons, not enough seats will be available.

Please tell me how to work this out.

  • statistics - ,

    ok, then the question is what is the probability of all 17 wanting seats?

    Pr(all)=.89^17

    Pr not enough seats=Pr(all)

  • statistics - ,

    Sorry, forgot the last line - Find the probability that not enough seats will be available.
