After observing the decisions of other players. C. Without knowledge of the payoffs. D. Without considering their own preferences. What is the "minimax strategy" in game theory? A. A strategy that minimizes the maximum possible loss. B. A strategy that maximizes the minimum possible gain.
C. A strategy that balances risk and reward. D. A strategy that aims for an equal distribution of payoffs. What does the "zero-sum game" concept imply? A. The total payoff to all players is always zero. B. One player's gain is exactly balanced by another player's loss. C. Players can never achieve a positive sum of payoffs. D.
