Key learning points

1. A set of results can be critically evaluated to help determine if a game/object is fair
2. Different samples and may affect your perception of fair
3. The experimental probability of an outcome/event can be calculated from a set of results
4. Experimental probabilities can be used to estimate an event may occur in a set number of trials

Keywords

• Experimental probability - The frequency of an outcome from an experiment can be used to produce an experimental probability. This is sometimes referred to as relative frequency.

• Fair - A trial or experiment is fair if each outcome has an equal chance of happening. Each outcome is said to be equally likely.

• Bias - If there is bias, in a trial or experiment, the outcomes are not equally likely.
