Consider a zero-sum 2-player normal form game given by the matrix -3 5 3 10 A = 7 8 4 5 4 -1 2 3 for player Alice and the matrix B= -A for the player Bob. In the setting of pure strategies: (a) State explicitly the security level function for Alice and the security level function for Bob. (b) Determine a saddle point of the zero-sum game stated above. (c) Show that this saddle point (from (2)) is a Nash equilibrium.
