Mixed Strategy – Definition & Examples

Definition: A strategy where a player randomly chooses between actions according to a probability distribution.

Detailed Explanation

When no pure strategy (always doing the same thing) is optimal, players randomize. In rock-paper-scissors, playing each option 1/3 of the time is the equilibrium mixed strategy—any predictable pattern can be exploited. Mixed strategies ensure unpredictability when predictability would be punished.

Real-World Example

Penalty kicks in soccer: if the kicker always went right, the goalie would always dive right. Randomizing keeps the goalie guessing. Similarly, tax audits randomize to prevent systematic evasion.

AP Economics Relevance

Mixed strategies appear in advanced game theory. Basic AP coverage focuses on pure strategies, but mixed strategies explain randomization.

How to Remember It

A strategy where a player randomly chooses between actions according to a probability distribution. A useful definition should do more than name the concept. Try to describe Mixed Strategy – Definition & Examples in your own words, give one real-world example, and name one situation where confusing it with a related term would lead to the wrong answer. That habit is especially helpful for AP, IB, and introductory college economics.
