Consider a train that starts from the LA-Union station. Let I", denote the number of people that get into the train from the station m. Assume that Im are independent and Poisson with parameter Am. Each person entering from the station m will, independent of everything else, get off at the station n with probability Pam. Also, 2 Pm.\" = 1. Let Gn be the number of people getting o' the train at the station n. (3.). Calculate lE [Ga]. (b). What is the distribution of G\"?. (c). What is the joint distribution of GH and Gk? \">171
