Consider the following game: COLIN F M N R Up 1, 1 2,2 3, 4 9, 3 ROWENA Down 2.5 3.3 1,2 7. 1 a. Find all pure-strategy Nash equilibria of this game. b. Now find a mixed-strategy equilibrium of the game. What are the players' expected payoffs in the equilibrium? (Hint: Try to plot Colin's expected payoff against the p-mix of Rowena. You will find that Colin will not use all the strategies.)
