Q2 The waiting time, in hours, between successive speeders spotted by a radar unit is a continuous ran- dom variable with cumulative distribution function [0, x < 0, F(x) = (1-e-8=, x>0. Find the probability of waiting less than 12 minutes between successive speeders (a) using the cumulative distribution function of X; (b) using the probability density function of X.
