Question 78730
An airline reports that it has been experiencing a 15% rate of no-shows on advanced reservations. Among 150 advanced reservations, find the probability that there will be fewer than 20 no-shows.
-----------
It is a binomial problem with n=150, p=0.15, 0<=x<=19
If you have a TI calculator with a stat capability use
binomcdf(150,0.15,19)=0.250928...
