Data from 14 cities were combined for a​ 20-year period, and the total 280 ​city-years included a total of 107 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:
