The joint pmf of X and Y is f(x, y) = 1/6, 0 ≤ x + y ≤ 2, where x and y are nonnegative integers. (a) Sketch the support of X and Y. (b) Record the marginal pmfs fX(x) and fY(y) in the “margins.” (c) Compute Cov(X, ...An insurance company sells both homeowners’ insurance and automobile deductible insurance. Let X be the deductible on the homeowners’ insurance and Y the deductible on automobile insurance. Among those who take both ...Let X and Y have the joint pdf f(x, y) = x + y, 0 ≤ x ≤ 1, 0 ≤ y ≤ 1. (a) Find the marginal pdfs fX(x) and fY(y) and show that f(x, y) ≠ fX(x)fY(y). Thus, X and Y are dependent. (b) Compute (i) μX, (ii) μY, ...Let X and Y have a bivariate normal distribution with μX = 70, σ2X = 100, μY = 80, σ2Y = 169, and ρ = 5/13. Find (a) E(Y | X = 72). (b) Var(Y| X = 72).
