Solution 1

To solve this game using the iterative elimination of strongly dominated strategies, we first need to identify if any player has a strategy that is always worse than another strategy, regardless of what the other players do.

Let's start with Player 1. We can see that strategy M strongly dominates strategy D because for every possible action of Player 2, the payoff of M is always higher than D. Therefore, we can eliminate strategy D for Player 1.

Next, let's look at Player 2. After eliminating strategy D for Player 1, we can see that strategy B strongly dominates strategy A for Player 2 because for every possible action of Player 1, the payoff of B is always higher than A. Therefore, we can eliminate strategy A for Player 2.

Finally, let's look at Player 3. After eliminating strategy D for Player 1 and strategy A for Player 2, we can see that strategy R strongly dominates strategy L for Player 3 because for every possible action of Player 1 and Player 2, the payoff of R is always higher than L. Therefore, we can eliminate strategy L for Player 3.

After the iterative elimination of strongly dominated strategies, we are left with strategy M for Player 1, strategy B for Player 2, and strategy R for Player 3. Therefore, the outcome that survives the iterative elimination of strongly dominated actions is (M, B, R).

Solution 2

To solve this game using the iterative elimination of strongly dominated strategies, we first need to identify if any player has a strategy that is always worse than another strategy, regardless of what the other players do.

Let's start with Player 1. We can see that strategy M strongly dominates strategy D because for every possible action of Player 2, the payoff for M is always higher than for D. Therefore, we can eliminate strategy D for Player 1.

Next, let's look at Player 2. After eliminating D for Player 1, we can see that strategy B strongly dominates strategy A for Player 2. This is because for every possible action of Player 1, the payoff for B is always higher than for A. Therefore, we can eliminate strategy A for Player 2.

Finally, let's look at Player 3. After eliminating D for Player 1 and A for Player 2, we can see that strategy R strongly dominates strategy L for Player 3. This is because for every possible action of Player 1 and Player 2, the payoff for R is always higher than for L. Therefore, we can eliminate strategy L for Player 3.

After these eliminations, we are left with one strategy for each player: M for Player 1, B for Player 2, and R for Player 3. Therefore, the outcome that survives the iterative elimination of strongly dominated actions is (M, B, R).
