Let X1, X2, and X2 be continuous with a joint pdf f(X1, X2, Xz) = SC, 0 < xz < x2 < X1 < 1 lo, otherwise = Since each variable is dependent on the other variables, our bounds of integration when determining marginal density functions becomes the other variables. For instance, to calculate the marginal pdf of Xz, becomes 2 fx, (x1) = 6*26*2 c dxzdx2 = And the area under the curve becomes 1 Areaf(x2.x2-xg) = S. Lo ? D*2 c dxzdxzdx, = a. Find the value of "c" that makes this a valid probability density function b. Calculate the marginal pdf fx, (x2) c. Calculate the joint pdf fx, x, (x1,x2) d. Calculate the conditional pdf of X3 given (x1,x2) = (x1,x2)
