The random variables X and Y, representing the weights of creams and toffees in 1-kilogram boxes of chocolates containing a mixture of creams, toffees, and cordials, have the joint density function(a) Find the probability density function of the random variable Z = X + Y.(b) Using the density function of Z, find the probability that in a given box the sum of the creams and toffees accounts for at least ? but less than ? of the totalweight. The random variables X and Y, representing the weights of creams and
