Assume that the cumulative distribution function of random variable X is given by 0, x<-2, 1/3, -2 < x < 0, 0≤x < 2, 1/2, 1 x > 2. Fx (x) = (a) Find P (X ≤ 1). (b) Find the probability mass function of X. (c) Find the probability mass function and the cumulative distribution function of Y = 2 - X. (d) Is it possible to find a function f so that if we define Z = f(X), then Z has two different values a and b, with P (Z = a) = P(Z = b) = 1/2? Justify your answer!
