A candy company distributes boxes of chocolates with a mixture of creams, toffees, and corals, Suppose that the weight of each box is ; pound, but the individual weights of the creams, toffons, 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 those variables is shown below Complete parts (a) through (c) f(x y) . 38xy. OsX53.0sys3. xtys - elsewhere (a) find the probability that in a given box the cordials account for more than ; of the weight The probability is (Simplify your answer.)
