Definition: Probability

Definition: Probability

• An experiment is a process that produces an observation.
• An outcome is a possible observation.
• The set of all possible outcomes is called the sample space.
• An event is a subset of the sample space.

The probability of any outcome is the long-term relative frequency of that outcome.
