Key Facts
- Sample Space (S): The set of all possible outcomes of an experiment
- Outcome: A single result from an experiment
- Event: A subset of the sample space (one or more outcomes)
- Equally Likely Outcomes: Each outcome has the same probability of occurring
- The number of outcomes in the sample space is denoted as n(S)
- For equally likely outcomes: P(event) = n(event) / n(S)
