1. Answer the following questions. (a) Check whether or not each of f1(x), f2(x) is a legitimate probability density function f1(x) = ( 0.5(3x − x3) 0< x < 2 0 otherwise f2(x) = ( 0.5(3x − x2) 0< x < 2 0 otherwise (b) Let X denote the resistance of a randomly chosen resistor, and suppose that its PDF is given by f(x) = ( kx 8 x 10 0 otherwise (i) Find k and the CDF of X, and use the CDF to calculate P(8.6 X 9.8). (ii) Find the conditional probability that X 9.8 given that X # 8.6.
