For each of the following payoff matrices, check if it has a Pure Strategy (Saddle Point)? If yes, provide all possible strategy-pairs (in case there is more than one) and the corresponding value of the game. (a) [[7,1,5,9],[1,0,3,2],[6,3,6,4]] [[4,-3,7,-4,9],[5,-2,-1,-2,0],[6,-8,8,-2,-3]] (b)

2. Show that the payoff matrix below does not have a pure strategy (or saddle point), then use the algebraic method (computing v_(1) and v_(2) ) to find the solution. [[1,3],[4,0]]
