**TLDR:** A fundamental mathematical concept that quantifies the likelihood of an event occurring.

<p>Probability is the most fundamental way of modeling uncertainty numerically. It expresses how likely an event is to occur on a scale between 0 and 1, making random processes mathematically analyzable. Machine learning, statistics, risk analysis, and decision systems cannot be built properly without probabilistic thinking. From classification scores and Bayesian models to confidence estimation and uncertainty quantification, many methods depend on this foundation. Probability enables AI systems not only to ask what may happen, but also how confidently it may happen.</p>
