If he sees a green lightat an intersection, then 60% of time the next light is also green,and 40% of time the next light is red. However, if he sees a redlight, then 75% of time the next light is also red, and 25% of timethe next light is green. Let 1 = “green light” and 2 = “red light”with the state space {1, 2}.
