1. Experiments are fundamental for determining probabilities and can be repeated under identical conditions.
2. Each repetition of an experiment is called a trial.
3. The set of all possible outcomes of an experiment is called the sample space.
4. Events are subsets of the sample space and can consist of one or more outcomes.
5. Experiments can be classified as independent or dependent based on whether the outcome of one trial affects another.
