(show the numerator and denominator using the counting rules; no need to complete the calculations)

A recent report indicates that about 1 in every 200 Americans are in prison. Use this information and the Poisson distribution to determine the approximate probability that at most three people in a random sample of n = 500 Americans are currently in prison.(circle your answer)
