Question 1004113
Air America is considering a new policy of booking as many as 170 persons on an airplane that can only seat 150. Past studies have revealed that only 85% of the booked passengers actually arrive for the flight. Estimate the probability that if Air America books 170 persons, not enough seats will be available. 
------------
Binomial Problem with n = 170 and p(arrive) = 0.85
-----
P(x >= 151) = 1 = binomcdf(170,0.85,150) = 0.0953 = 9.53%
