: Let X And Y Be Random Variables Such That Var X 02 Var Y 72 And Cov X Y 7 Let A B C D Be Constants Find 1 (16.47 KiB) Viewed 115 times

Let X and Y be random variables such that Var(X) = 02, Var(Y) = 72, and Cov(X,Y) = 7. Let a, b, c, d be constants. Find Cov(aX + bY,cX + DY) in terms of the seven constants in this problem.
