A candy company distributes boxes of chocolates with a mixture of creams, toffees, and cordials. Suppose that the weights of the creams, toffees, and cordials vary from box to box, let X and Y represent the weights of the creams and toffees, respectively, and suppose that the joint density function of these variables is 0sxS 1,0 sys 1, S(x, y) = (24xy, x + ys1 0, elsewhere. a. Find the probability that in a given box the cordials account for more than % of the weight. b. Find the marginal density for the weight for the creams. c. Find the probability that the weight of the toffees in a box is less than 1/8 of a kilogram if it is known that the creams constitute % of the weight.

3. A candy company distributes boxes of chocolates with a mixture of creams, toffees,
and cordials. Suppose that the weights of the creams, toffees, and cordials vary from
box to box, let X and Y represent the weights of the creams and toffees,
respectively, and suppose that the joint density function of these variables is
f(x, y) = {24xy,
0,
0sxS 1,0 s y s 1,
x+ ys1
elsewhere.
a. Find the probability that in a given box the cordials account for more than ½ of
the weight.
b. Find the marginal density for the weight for the creams.
c. Find the probability that the weight of the toffees in a box is less than 1/8 of a
kilogram if it is known that the creams constitute ¾ of the weight.
