(a) Use LOTUS to express G(z) = E[zX] as a power series. (Your answer should look something like and λ > 0. k=0 where I left question marks for something that's missing.) (b) What is G(0)? (c) What is G(1)? (d) What is G'(z)? Give two answers: one is a series, the other is E[of something]. (e) What is G'(0)? (f) What is G'(1)? (g) What is G"(z)?
