- Probability - Wikipedia
Probability is a branch of mathematics and statistics concerning events and numerical descriptions of how likely they are to occur The probability of an event is a number between 0 and 1; the larger the probability, the more likely an event is to occur [note 1][1][2] This number is often expressed as a percentage (%), ranging from 0% to 100%
- Probability: the basics (article) | Khan Academy
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 of certain outcomes—how likely they are The analysis of events governed by probability is called statistics View all of Khan Academy’s lessons and practice exercises on probability and statistics

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)

The probability of an event is a number between 0 and 1 (inclusive) If the probability of an event is 0, then the event is impossible On the other hand, an event with probability 1 is certain to occur In general, the higher the probability of an event, the more likely it is that the event will occur

- Basic Concepts of Probability - GeeksforGeeks
Probability is defined as the likelihood of the occurrence of any event It gives a numerical value to the chance or likelihood of something happening Probability is generally denoted by P (E), where E represents the event It is expressed as a number between 0 and 1: 0 means the event is impossible, 1 means the event is certain, Values between 0 and 1 represent partial chances
- Probability theory | Definition, Examples, Facts | Britannica
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 any one of several possible outcomes The actual outcome is considered to be determined by chance
