Question
(In this and all other questions in which a game matrix is given, Player 1 chooses the row, Player 2 chooses the column, and if there is a Player 3, she chooses the matrix.)Which is true for the following game according to the solution concept of iterated elimination of strongly dominated strategies? A B C Da 4,3 -2,0 2,2 1,6b 6,-1 4,-1 0,-2 0,-2c 5,9 2,6 1,7 5,7 None of the other alternatives is true. The strategy profiles (b,A) and (b,B) solve the game. The unique strategy profile that solves the game is (c,A). The unique strategy profile that solves the game is (b,A). Player 1 is guaranteed a payoff of 6. Strategy profiles (a,D) and (b,D) solve the game.
Solution
To solve this game using the concept of iterated elimination of strongly dominated strategies, we first need to identify if there are any strategies that are strongly dominated.
A strategy is strongly dominated if there is another strategy that always results in a higher payoff, regardless of what the other player does.
Looking at the game matrix, we can see that for Player 1, strategy 'b' strongly dominates strategy 'a' because in every column, the payoff for 'b' is higher than for 'a'. Similarly, strategy 'c' strongly dominates 'a'. Therefore, we can eliminate strategy 'a' for Player 1.
For Player 2, strategy 'A' strongly dominates 'B' and 'C' because in every row, the payoff for 'A' is higher than for 'B' and 'C'. Therefore, we can eliminate strategies 'B' and 'C' for Player 2.
After eliminating these strategies, we are left with the following reduced game matrix:
A D
b 6,-1 0,-2 c 5,9 5,7
In this reduced game, for Player 1, strategy 'b' strongly dominates 'c' in response to 'A', and 'c' weakly dominates 'b' in response to 'D'. For Player 2, 'A' weakly dominates 'D' in response to both 'b' and 'c'. Therefore, we can't eliminate any more strategies.
The strategy profiles that solve the game are therefore (b,A) and (c,A). So, the correct answer is "The strategy profiles (b,A) and (c,A) solve the game."
