You can put this solution on YOUR website! an airline estimates that 98% of people booked on their flight actually showed up. if airline books 76 people on a flight for which the maximun number is 74, what is the probability that the number of people who showed up will exceed the capacity of the plane
-------
Binomial Problem with n = 76 ; p(arrive)=0.98 ; p(don't) = 0.02
--------
P(x > 74) = 1 - P(0<= x <=74) = 1 - binomcdf(76,0.98,74) = 0.55
