For each of the four games in Exercise U1, identify whether the game is zero-sum or non-zero-sum. Explain your reasoning.

As in Exercise S3 above, use the minimax method to find the Nash equilibria for the zero-sum games identified in Exercise U2.

Find all Nash equilibria in pure strategies in the following games. Describe the steps that you used in finding the equilibria.
