Among 15,378 Delta airline passengers randomly selected, 3 were bumped from a flight against there wishes (based on data from the us dept of transportation) find the probability that a random selected passenger is involuntarily bumped. Is such bumping unusual? Does such bumping pose a serious problem for Delta passengers in general? why or why not? what is the method used to obtain the probability?

3/15,378 = .0002
That should help you answer the questions.
