Consider the following strategic-form game. Player 2 A B A (0,0) (1,-1) Player 1 B (-1,1) (2,2) (a) Find the pure-strategy Nash equilibria. (b) Find the mixed-strategy Nash equilibrium. (c) Show that the pure-strategy Nash equilibria are evolutionary stable. Recall that a strat- egy x* is evolutionary stable if for any other strategy y * r": (i) u(x', r') > u(y, I* ), or (ii) (a) u(r*, r') = u(y, r*) and (b) u(x',y) > u(y, y). Also, show that the mixed-strategy Nash equilibrium is not evolutionary stable
