i know there exists a formula expressing the covariance

E[(X-E(X))(Y-E(Y))] between X and Y, involving a double integral of

F_X(x), F_Y(u) and F_XY(x, y), the CDF of X, Y and (X,Y), but I can't

remember it and didn't found

it with google. Does someone remember this formula?

Thanks for the help,
