Question 859797: I have a probability question that i do not understand how to do.
Client query requests arrive independently at a database server at an average rate of 4.5 queries per minute. For a randomly selected one-minute interval, what is the probability that exactly 3 query requests will arrive?

POISSON Distribution
P(x; μ) = (e^(-μ) (μ^x) / x! where μ is the average number of successes
e%5E%28-4.5%29%284.5%29%5E3%2F3%21
P(x=3) = .1687
