Suppose that X₁, X2, X3 are mutually independent random variables with the respective moment generating functions, Mx, (t) = est¹², Mx₂(t) = e²t + 3t², and Mx, (t) = (-)². a) Calculate the probability that X₂ is between 2 and 4, P (2 < X₂ < 4). State with parameter(s) the probability distribution of Y = X₁ + X₂. b)
