The dilemma in a prisoner's dilemma is that: Multiple Choice only one player has a dominant strategy, but the other player is uncertain about what to do. the players would be better off if they both played a dominated strategy. the players may be trapped in a game they don’t know how to play. the outcome is random, so players are uncertain about which strategy to play.
