Chapter 8.5, Problem 21MS

Colin and Tubbes. When first grader Cohn comes home from school each day, his pet hippo Thbbes is waiting to greet him. Because Tubbes is so large and enthusiastic, Cohn does not enjoy these blubbery greetings, so he tries to avoid them by switching between the back door and the front door to thwart Tubbes. When Colin succeeds in avoiding Tubbes, he feels a satisfaction “gain” of 5. If Cohn enters the front door and finds Tubbes waiting, he feels a satisfaction gain of $-5$ (in effect, a slobbery loss). If Cohn enters the back door and finds Thbbes waiting, his satisfaction loss is only $-2$ because his mother’s presence in the kitchen helps keep Tubbes under control. Create a payoff matrix that illustrates this situation. (Let the top row give Colins possible payoffs if he uses the front door. Let the first column give the payoffs if Tubbes is waiting at the front door.)
