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)

how do I do this????

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%

Might be subtraction.so I don't know this.
