The payoff matrix below shows the payoffs for Stefan and Imani in a two strategy game. In the mixed strategy equilibrium, Stefan will play strategy Up with a probability of 1/5 and strategy Down with a probability of 4/5, and Imani will play strategy Left with a probability of 2/5 and strategy Right with a probability of 3/5.     What is Stefan's expected payoff in the mixed strategy equilibrium?
