The partition theorem says that if Bn is a partition of the sample space then EX = X n EXjBnP(Bn) Now suppose that X and Y are discrete RV's If y is in the range of Y then Y = y is a event with nonzero probability, so we can use it as the B in the above1 Show that if X and Y are independent random variables with the moment generating functions M X(t) and M Y (t), then Z = X Y has the moment generating function, M Z(t) = M X(t)M Y (t) 2 Find a variance of the random variables in Example 1 Finally, we can also define the conditional expectation, E(X Y), and conditional variance, E(XMathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields It only takes a minute to sign up
