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.

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

Pr(all)=.89^17

Pr not enough seats=Pr(all)

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