Suppose that X is a random variable with probability density function fx(x) and cumulative distribution function fx(x). Additionally, suppose X can only take on positive values; that is, P(X > 0) = 1. Show that the following equality holds: ro 8 [1 - Ex(x)]dx = tfx(t)dt Hint: Write [1 Fx (x)] as an integral of fr(t) to get a double integral on the left-hand side. Then, switch the order of integration.
