Which mathematical concept includes determining the probability of an event?

The correct choice focuses on statistics, which is fundamentally concerned with the collection, analysis, interpretation, presentation, and organization of data. One of the primary concepts within statistics is probability, which quantifies the likelihood of certain events occurring.

When determining the probability of an event, you assess the ratio of favorable outcomes to the total number of possible outcomes. This concept is crucial in various fields, including science, economics, and everyday decision-making. In contrast, algebra, geometry, and calculus primarily deal with different aspects of mathematics that do not specifically focus on the analysis of data and the likelihood of events.

Algebra involves operations and relationships between numbers and symbols. Geometry studies the properties and relationships of points, lines, surfaces, and solids. While calculus looks at changes and the concept of limits, none of these branches directly encompass the calculation of probabilities, which is a distinctive characteristic of statistics.
