WebProof. Intuitively, the expected cost of a mixed strategy is an average of the costs of the pure strategies in its support, weighted by its probability distribution; but an average cannot be less than its smallest argument.

Let p, q, and 1 – p – q be the probability that a player chooses R, P, and S respectively. We first argue that we must look only at completely mixed strategies (that is, mixed strategies that put a positive probability on every available pure strategy).

In the Prisoner's Dilemma game pictured to the right, the only Nash equilibrium is (D, D). Since both players use the same strategy, the equilibrium is symmetric. Symmetric equilibria have important properties.
