I am confused about how to solve this problem.

1. In the following payoff matrix, player 1's payoff is the rst entry and player 2's payoff is the second entry. For example, if player 1 chooses down and player 2 chooses right, then player 1's playoff is 13 and player 2's payoff is 5. Player 2 Left Right Up 9,4 15,3 Playerl Down 12,6 13,5 The Nash equilibrium is for player 1 to choose up and player 2 to choose left
