Suppose that X has density function fx (x) : 2e-2x for x > 0 (and fx (x) = 0 otherwise). Also suppose that the conditional density of Y given X = x (where x > 0) is given by fyjx (y | x) = 2 for 0 < y < x (and fyjx (y | x) = 0 otherwise). Use the Partition Theorem (or otherwise) to determine E (Y), the expected value of Y.

Suppose you approach me after I pay for my items and ask: "Did you save any money?" If I answer "no", then you know I didn't save $20 and thus the chance of saving $20 changes from the unconditional chance 24% to the conditional chance 0%. However, if I answer "yes" my chance of saving $20 would get higher. What would be the conditional chance of saving $20 if you knew I got a discount? Mathematically, we seek: P(X = 20|X > 0 ). Even though it looks weird, it is just a conditional probability. Find it. P(X = 20|X > 0) = P(X = 20 and X > 0) / P(X > 0) = Hint: P(X = 20 and X > 0) be read off the table by identifying possible values where the event (X = 20 and X > 0) is true, don't use the multiplication rule.
