Consider the discrete random variable X such that 0.5, if x = -2 P(X = I) = 0.2, if x = 0.2 0.3, if x = 7 0 , otherwise Use the discrete version of the Inverse Transform method from class and the Unif(0, 1) pseudo-random number U = 0.99 to generate one observation X coming from this p.m.f. O X=-2 OX = 0.2 OX =3 OX = 7
