Suppose that the random variables X, and X, have joint probability density function h(X1, X2) = 9x x2, -X2

Suppose that the random variables Xl and X 2 have joint probability density function = 9XIX2, X2 < Xl < X2, and O < xz < 1. a. b. c. d. Find the marginal p.d.f.s of Xl and X 2 and show that these random variables are not independent. Find the correlation coefficient for Xl and X Find the jointp.d.f. of Yl = I and Y2 = X 2. Are Yl and Y2 independent?
