Question
Suppose that X has density function fx (x) = Also suppose that the conditional density of Y given X = = x (where x > 0) is given by 2y fy|x (y|x) = 24 for 0 <y<x (and fyx (y | x) = 0 otherwise). x² -2x = 2e for x > 0 (and fx (x) = 0 otherwise). Using the Law of Total Expectation (Partition Theorem for Expectation), or otherwise, determine E (Y) , the expected value of Y.
