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", …

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).

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 …

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 …

More generally, if I have a set of n objects and choose one, with each one equally likely to be chosen, then each of the n outcomes has probability 1/n, and an event consisting of m of the outcomes has …

Dec 6, 2025 · The probability of an event E, denoted by P (E), is a number between 0 and 1 that represents the likelihood of E occurring. If P (E) = 0, the event E is impossible.

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 …

This page introduces probability and random variables, laying the foundation for understanding key concepts in statistics and probability theory.

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.
