Game theory is:A. a strategy that requires cooperation when multiple parties are involved.B. a methodology to accomplish winning results in games of chance.C. the study of strategy and strategic behavior.D. focused on competition between two distinct rivals.

Game theory is the study of strategy and strategic behavior. It is assumed that the parties involved are rational. The payoff of a player of a game is determined by the actions of others in the game.

A popular example of game theory is the prisoners dilemma.

A game theory can involve more than two players.

An example of prisoners dilemma:

There are two prisoners - if both confess to a crime, they both get 5 years in prison. If both prisoners don't confess they are set free. If one confess and the other doesn't, the prisoner that confesses 2 years in prison while the other prisoner that didn't confess gets 10 years in prison.

The dominant strategy which is the best option for the prisoner regardless of what the other prisoner does is to confess.

The Nash equilibrium is for both prisoners to defect.
