The actual results consisted of 197 city-years with 0 homicides; 70 city-years with one homicide; 12 city-years with two homicides; 1 city- with three homicides; 0 city- with four homicides. Compare the actual results to those expected by using the Poisson probabilities. Does the Poisson distribution serve as a good tool for predicting the actual results? P(0)=0.7072 P(1)=0.2450; P(2)=0.0424; P(3)=0.0049; P(4) =0.0004

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e.g. 98.7654). x f(x) 0 1 2 3
