If either player plays a mixed strategy other than \((1/2,1/2)\) then the other player has an incentive to modify their strategy. And that doesn't mean that it always has to be 50-50. For finite discrete demand distribution, we give a sufficient and necessary. If we admit mixed strategies (where a pure strategy is chosen at random, subject to some fixed probability), then there are three Nash equilibria for the same case: two we have seen from the pure-strategy form, where the probabilities are (0%, 100%) for player one, (0%, 100%.
