The following model can be used to describe the number of women (moth- ers and daughters) in a given area. The number of mothers is a random variable X E Po(A). Independently of the others, every mother gives birth to a Po(u)-distributed number of daughters. Let Y be the total number of daughters and hence Z = X +Y be the total number of women in the area. (a) Find the generating function of Z. (b) Compute EZ and Var Z. The following model can be used to describe the number of women (moth- ers and daughters) in a given area.
