A candy company distributes boxes of chocolates with a mixture of creams, toffees, and cordials. Suppose that the weight of each box is kilogram, but the individual weights of the creams, toffees, and cordials vary from box to box. For a randomly selected box, let X and Y represent the weights of the creams and the toffees, respectively, and suppose that the joint density function of these variables is as shown. Find the covariance between the weight of the creams and the weight of the toffees in these boxes of chocolates. 1 384xy, 0≤x≤ f(x,y) = 0, elsewhere x+ys.
