Question: To underscore that the formulas can be used only if you end up with legitimate strategies, consider the game with matrix
(a) Does this matrix have a saddle in pure strategies? If so find it.
(b) Find A-1. (c) Without using the formulas, find an optimal mixed strategy for player II with two positive components.
(d) Use the formula to calculate Y∗. Why isn't this optimal? What's wrong?
