Data from 14 cities were combined for a 20-year period, and the total 280 city-years included a total of 112 homicides. After finding the mean number of homicides per city-year, find the probability that a randomly selected city-year has the following numbers of homicides, then compare the actual results to those expected by using the Poisson probabilities:

Homicides each city-year	a. 0	b. 1	c. 2	d. 3	e. 4
Actual results	187	76	15	2	0
