4.1. Suppose X and Y are independent random variables, which are jointly continuous. 1. Show carefully that the distribution of 'X + Y given X = x' is equal to the distribution of the random variable x +Y. Hint: Consider the change of variables h(x, y) = (x,x+y). 2. Suppose X and Y each have an exponential distribution with parameter a, find the joint p.d.f of X and X + Y. 3. In the situation of (ii) above calculate E[X | X + Y].
