- Let U1,U2 and U3 be mutually independent, uniform random variables on [0, 1]. LetX = min{U1,U2,U3}, Y = max{U1,U2,U3}.Find E[X | Y = y].arrow_forward4. Let X, Y be independent random variables. Prove that E(XY)= E(X) E(Y) and hence show that V(X+Y) = V(X)+V(Y).arrow_forwardLet Y₁ = (x,-X₂), where X, and X₂ are independent random variables and each of them X, 2 is distributed as x² (2). Find the p.d.f. of Y₁.arrow_forward
