In a contingency table, a conditional … WebOct 19, 2024 · 1 Answer Sorted by: 2 X = N + c = g Y + c If X and Y are independent then X would be independent of itself which makes it a constant r.v. Hence, unless X and Y are constant there is no scope for X and Y to be independent. E X Y = E ( g Y + c) Y = g E Y 2 + c E Y. You will need E Y 2 to find E X Y.
