23. The random variable X has the "swish" pdf (probability density function) given by ſ½(1-x) if 0 ≤ x ≤ 1 a(x² - 1) if 1<x< 2 f(x) = (a) Find a so f(x) is a valid probability density function. (b) Set up, but you need not evaluate, integral(s) to compute P P ( 1/2 < X < 1/1). (c) Set up, but you need not evaluate, integral(s) to compute E(X).
