Suppose that A and B are roommates. Each of them can choose whether to plant flowers in the garden. If they both plant, each will get a payoff of 30. If one plants, and the other does not, the one who plants will get -20 (because it is hard work) and the one who does not will get 45. If neither of them plants any flowers, each will get a payoff of 0.

a) What outcome do you think is most likely? Why?

b) What is in common between this situation and the Prisoner's Dilemma? Why?
