The probability is a number between 0 and 1; the larger the probability, the more likely the desired outcome is to occur. For example, tossing a coin twice will yield "head-head", "head-tail", "tail-head", …

Statistics and probability Course: Statistics and probability > Unit 7 Lesson 1: Basic theoretical probability Intro to theoretical probability Probability: the basics

Probability is all about how likely is an event to happen. For a random experiment with sample space S, the probability of happening of an event A is calculated by the probability formula n (A)/n (S).

How likely something is to happen. Many events can't be predicted with total certainty. The best we can say is how likely they are to happen,...

Jan 2, 2025 · We do that by assigning a number to each event (E) called the probability of that event (P (E)). The probability of an event is a number between 0 and 1 (inclusive). If the probability of an …

Feb 14, 2026 · Statistics - Probability, Random Variables, Distributions: Probability is a subject that deals with uncertainty. In everyday terminology, probability can be thought of as a numerical …

Oct 3, 2025 · In this section, you will explore the fundamental concepts of probability, key formulas, conditional probability, and Bayes' Theorem. By the end, you'll have a clear understanding of how …

Thus, Probability theory is the branch of mathematics that deals with the possibility of the happening of events. Although there are many distinct probability interpretations, probability theory interprets the …

Probability is a fundamental concept in mathematics and statistics that deals with the likelihood of events occurring. It provides a framework for quantifying uncertainty and making predictions based on …

Feb 14, 2026 · Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.
