In Exercise 5.9, we determined that f (y1, y2) = 6(1 y2), 0 y1 y2 1, 0, elsewhere is a valid joint probability density function. Find a the marginal density functions for Y1 and Y2. b P(Y2 1/2|Y1 3/4). c the conditional density function of Y1 given Y2 = y2. d the conditional density function of Y2 given Y1 = y1. e P(Y2 3/4|Y1 = 1/2).
