Suppose U ∼ Uniform([0, 1]) and the conditional distribution of X given that U = p is Binomial(n, p). Find E(X) and E(X^2). (Hint: You can compute both easier by using the law of iterated expectations. Furthermore, if you need to compute E(X^2|U = p), you can compute this easily using the variance formula).
