A candy company distributes boxes of chocolates with a mixture of creams, toffees, and cordials. Suppose thatthe weight of each box is 1 kilogram but the individual weights of the creams, toffees, and cordials vary fromthe box to box. For a randomly selected box, Let X and Y represent the weight of the crems and the toffees,respectively, and suppose that the joint density function of these variables is| 24xy 0
