Question 3 Consider an application of the Prisoner's Dilemma game where two countries in a cartel decide whether to Cooperate or Defect. If both choose to follow the cartel agreement and continues cooperating with each other, each receives a payoff of 2. If both decide to defect on each other, they both get -2. If one cooperates and the other defects, the first one loses 10 (she receives -10) while the other gets 0. Denote the probability of cooperating for Player 1 as p and for Player 2 as q. How much does Player 1 earn in the mixed-strategy Nash equilibrium of this game? Write your answer as a decimal with 2 decimal places (e.g. 0.25)
