An outcome is one possible result of an experiment, like rolling a 3 on a die or landing on blue on a spinner.

When you list every outcome that could happen, you get the full 'sample space.' A coin has 2 outcomes: heads or tails. A six-sided die has 6 outcomes: 1 through 6.

A game is fair when every player has an equal chance of winning. If a spinner has 3 equal sections for 3 players, that is fair. If one section is bigger, it is unfair.

Understanding outcomes helps you check whether a game or experiment is truly fair before you play.
