1. Continuous random variables 0 ≤X ≤ 2 and 0 ≤ Y ≤ 2 have joint probability density function 3x² +4y fx,y(x, y) = 32 (a) Find and simplify a formula for the marginal density function fx(x). (b) Compute E(XY). (c) Compute P(Y> 2x). Draw a picture of the full range and the event Y > 2X to help you understand this problem.
