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", …

Explore what probability means and why it's useful. Probability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the probabilities …

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, using the idea of probability. When a coin is tossed, there are …

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).

Dec 23, 2025 · Probability theory, a branch of mathematics concerned with the analysis of random phenomena. The outcome of a random event cannot be determined before it occurs, but it may be …

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 …

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 …

Dec 26, 2025 · Probability is a subject that deals with uncertainty. In everyday terminology, probability can be thought of as a numerical measure of the likelihood that a particular event will occur.

Dec 17, 2025 · A Probability of 0 means an event is impossible, while a probability of 1 means it is certain. It covers fundamental concepts, formulas, and theorems to analyse outcomes in daily …
