What is the Nash equilibrium to this game? b. Does either player have a dominant strategy? c. What is the pure strategy Nash Equilibria of this game.d. This game has a mixed strategy Nash Equilibrium. Calculate the probabilities in which both William and Leowill play their respective strategies in equilibrium. Note: I am only looking for the probabilities – not the expected payoffs.
