Answer:
A strictly dominant action produces: a higher payoff than any other action the player can use for every possible action of the other players.
Step-by-step explanation:
A strictly dominant action does not play fair. Here, there is no equality because strict dominance requires all payoffs to be strictly greater.
A strictly dominant strategy is that strategy that always provides greater utility to a the player, no matter what the other player's strategy is.
A rational player will avoid a strictly dominated counterpart because if his opponent uses strictly dominated action he will be come out worse off regardless of which moves other players make.
