Answer 1

5- the best strategy to pick no matter which moves are chosen by the other player

Step-by-step explanation:

Dominant strategy is the best strategy to pick no matter which moves are chosen by the other player.

Dominant strategy is used in game theory to determine the best strategy for oligopoly firms in a collusion.

For example, in a prisoners dilemma, there are two prisoners, if both of them confess, they get 5 years in prison, if both of them don't confess, they are set free and if one confesses and the other doesn't, the prisoner that confesses gets 2 years in prison while the other who doesn't confess gets 10 years in prison.

The dominant strategy here is for the prisoners to confess. It is the best strategy regardless of what the other prisoner does.
