Which item is a possible result of a random process or trial?

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

Answer: (B)

Think about what happens in a single run of a random process. The specific result you observe each time is called an outcome. For example, when you flip a coin, the possible outcomes are heads or tails—the result of that one flip is an outcome, while probability tells you how likely each outcome is. An experiment is the whole procedure you perform, possibly involving multiple trials. The complement of an event means all outcomes that are not in the event, not a single result. So the item that is a possible result of a random process or trial is an outcome.
