In mathematics, what does probability measure?

• A. The total number of outcomes possible
• B. The distance between two points
• C. The likelihood of an event occurring
• D. The average of a set of numbers

Answer: (C)

Probability measures the likelihood of an event occurring. It quantifies how likely it is that a particular outcome will happen when a situation allows for multiple possible outcomes. For instance, in a simple scenario like flipping a coin, the probability of landing on heads is 0.5, indicating that there is a 50% chance of that outcome occurring. This concept is fundamental in statistics and decision-making under uncertainty, as it helps assess risks and predict future events based on past observations. By calculating probabilities, one can determine which outcomes are more or less probable, aiding in informed decision-making. The other options, while related to mathematical concepts, do not pertain to the definition of probability. The total number of outcomes is a separate concept that helps in calculating probability but does not describe what probability itself measures. The distance between two points is a geometric concept, while the average of a set of numbers refers to a statistical measure of central tendency. These definitions serve different purposes and should not be confused with the measure of likelihood that probability provides.
