Let X denote the diameter of an armored elec- tric cable
2.37    Let X denote the diameter of an armored elec- tric cable and Y denote the diameter of the ceramic mold that makes the cable. Both X and Y are scaled so that they range between 0 and 1. Suppose that X and Y have the joint density
( 1 and the toffees, respectively, and suppose that the joint density function of these variables is
 24xy,   0 ≤ x ≤ 1, 0 ≤ y ≤ 1, x + y ≤ 1,
f (x, y) =y ,    0 <> 1, 0,    elsewhere.
f (x, y) =0,        elsewhere.
Find P (X + Y > 1/2).
(a)Â Â Find the probability that in a given box the cordials account for more than 1/2 of the weight.
(b)Â Â Find the marginal density for the weight of 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 creams constitute 3/4 of the weight.
