Delta airline flights seats 340 people. An average of 5% of the people with reservations doesnt show up, so they overbook by 350. This system can be analyzed by using binomial distribution. n=350 and p=0.95

1) Find the probablity that 350 reservations there are more passangers then seats. Find P(at least 341 people with reservations show up)

1. The mean of the distribution of the number of passengers showing up is n*p and the standard deviation is sqrt [n*p*(1-p)]. Calculate those numbers.

Using these values and the normal distribution tool at
(Broken Link Removed) I get the probability of 341 or more booked passengers showing up to be 1.9%
