What does probability describe in general terms?

• A. The rate at which a result occurs.
• B. The average outcome of many trials.
• C. The likelihood that an event will occur.
• D. The total number of trials required to observe an event.

Answer: (C)

Probability is a measure of how likely something is to happen. It tells you the chance or odds of an event occurring, often expressed as a fraction, decimal, or percent between 0 and 1 (0% to 100% means impossible to certain). This differs from a rate (how often something happens per unit time), from an average outcome (the expected value you’d get if you repeated many times), and from the total number of trials needed to see something (which relates to waiting time). So probability describes the likelihood that an event will occur.
