which the commuter must stop on his way to work, and X, be the number of lights at which he must stop when returning from work. Suppose that these There are two traffic lights on a commuter's route to and from work. Let X, be the number of lights are independent, each with the pmf given in the accompanying table (so X,, X, is a random sample of size n = 2). 1 2 P(x,) 0.4 0.2 0.4 H = 1, o = 0.8 (a) Determine the pmf of T, = X, + X2- 1 3 4.
