Evert and Navratilova play tennis against each other. Suppose each player cannot see the opponent's action before taking his or her own action. That is, the tennis match is a simultaneous game. Evert's payoff is the left number in each cell. This game does not have a pure strategy Nash equilibrium. NAVRATILOVA DL CC DL 30,70 80,20 EVERT CC 90,10 20,80 Suppose Navratilova mixes DL and CC with equal chance, that is, she plays 50% of DL and 50% of CC (0.5DL + 0.5CC). Given that, what Evert's expected payoff of playing DL?
