This is probably what you;re expected to use here. If you don't even know what it is, you'll need some kind of introduction or at least refresher first. Try https://www.youtube.com/watch?v=Fk02TW6reiA or http://en.wikipedia.org/wiki/Poisson_distribution Th basic idea is that the expected number (lambda) is 3 and you need to use the formula to find out what the probability of getting a certain number is, given that lambda value.
