not choice 2, 5, or 6

Consider a 2-player game, played non-cooperatively as a one-shot simultaneously played game with full and symmetric information. Each player can choose to cooperate or compete. If both players to cooperate, each gets a payoff of 1; if both compete, each gets a payoff of -3. In case one chooses to cooperate and one chooses to compete, the former receives a payoff of 0, and the latter of 2. In a mixed strategy Nash Equilibrium, the probability of (cooperate, cooperate) being played is OO O 3 16 O 16 16 12 16 O1
