Question

Luggage is rarely lost on Northwest Airlines. Most flights do not lose luggage; in some one is lost; in a few two are lost; rarely three are lost, etc. Suppose that a random sample of 1,000 flights returns a total of 300 lost bags, then the average of lost bags per flight represents the lambda parameter of a Poisson distribution.

a) What is the probability that luggage will not be lost on the flight?
b) What is the probability that exactly one suitcase will be lost on a flight?
c) What is the probability that at least five bags will be lost on 10 flights?

Please show your procedure so I can understand it.
