Data from 14 cities were combined for a 20-year period, and the total 280 city-years included a total of 153 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 162 89 24 4 1 a. P(0)equals 0.5790 (Round to four decimal places as needed.) b. P(1)equals nothing (Round to four decimal places as needed.) Enter your answer in the answer box and then click Check Answer.
