Let X be N(0, 1), derive the moment generating function of X
Use integration to derive the moment-generating function MX (t) where fX (x) = (1/3) e^(−x/3) for x > 0. (Since we are maily interested in t near 0, assume that t < 1/3 .) Then use MX (t) to compute E(X), E(X^2), V (X), and E(X^3).
If X has moment generating function M(t) = (e−t + et )/2, then what is E(X), and what is P(X = 1)
