Emergency 911 calls to a small municipality in Idaho come in at a rate of 6.9 calls every hour. Assume that the number of 911 calls is a random variable that can be described by a Poisson distribution. What is the probability of four 911 calls in the next hour? Round your answer three decimal places.
