2. Each outcome is mutually exclusive, meaning no two outcomes can occur simultaneously in a single trial.
3. The probability of any outcome ranges between 0 and 1, inclusively.
4. The sum of the probabilities of all possible outcomes in a sample space equals 1.
5. In complex experiments, each outcome can be represented as an ordered pair or tuple.
