Which term describes the probability model that describes what should occur in an experiment?

• A. Outcome
• B. Theoretical probability
• C. Experiment
• D. Complement of an event

Answer: (B)

The term that describes the probability model for what should occur in an experiment is theoretical probability. It’s the calculated forecast you make before doing trials, based on assumptions like all outcomes being equally likely. For a fair coin, the theoretical probability of heads is 1/2, because there are two equally likely outcomes. This differs from experimental probability, which comes from actual trials and may vary due to randomness. An outcome is a single result, an experiment is the procedure you perform, and the complement of an event is the probability of not that event, not the overall model.
