The unit interval is the set of all real numbers between 0 and 1, inclusive, and is often denoted as [0, 1]. It is a fundamental concept in mathematics, particularly in real analysis and probability theory, serving as a prototype for understanding continuous intervals and measuring probabilities of events.

Real numbers encompass both rational and irrational numbers, forming a complete and continuous number line that represents all possible magnitudes and positions. They are fundamental in mathematics, serving as the basis for calculus, analysis, and many other fields, allowing for precise measurement and calculation of continuous quantities.

Real analysis is a branch of mathematics that deals with the rigorous study of real numbers and real-valued functions, focusing on concepts such as limits, continuity, and convergence. It provides the foundational framework for calculus and is essential for understanding the behavior of functions and sequences in a real-number context.

Probability theory is a branch of mathematics that deals with the analysis and interpretation of random phenomena and the likelihood of various outcomes. It provides a framework for quantifying uncertainty and making predictions based on incomplete information, which is fundamental in fields ranging from statistics to quantum mechanics.
