help question 3;

Given two game-tables A and B as shown below where A and B are zero-sum games.

a) find method to find the Nash equilibria for game A. attached picture of the tables.

b) For game B,

1. Use minimax method to show that game B does not have a Nash equilibria.
2. Show the simplified game that you obtain when you use dominance strategies to eliminate dominated strategies in table B for both Row and Column.
3. Find the Nash equilibrium in part (ii) and state the optimal strategy.
