• Example: Let the number of men and women entering a post office in a certain interval be two independent Poisson random variables with parameters and , respectively. Find the conditional probability function of the number of men given the total number of persons.
Solution: Let N, M, K be the total number of men, women, and persons entering the post office. Note that K = M+N and M, N are independent. So we have K is also Poisson with parameter +.
pN|K(n|k) = P(N=n)P(M=k-n)/P(K=k)=
