Let X and Y be identically distributed independent random variables such that the moment generating function of X + Y is M(t) = (0.25e^-4t + 0.25e^4t + 0.5)^2 for -∞ < t < ∞. Calculate Pr[X ≤ 0]. 0.5

The moment generating function of the random variable X is given by Mx(t) = exp{2e^t - 2} and that of Y by My(t) = (3/4e^t + 1/4)^10. Assuming that X and Y are independent, find (a) P{X + Y = 2}. (b) P{XY = 0}. (c) E(XY).
