Then E(XY) = E(X^2) = 1 . On the other hand, E(Y|Z) = E(Y) = 0 , so E(XE(Y|Z)) = 0 ...Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this siteJan 29, 2019 · Then XY X Y is a discrete random variable taking values in the set T T. Now suppose I ask you what the probability of XY X Y taking the value z z is. Well clearly if X = x X = x, then Y Y must equal z/x z / x. And since X X must take some value, we must have that. P(XY = z) = ∑x∈S P(X = x and Y = z/x). P ( X Y = z) = ∑ x ∈ S P ( X = x ...
