Probability concerns 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 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).
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 tells us how often some event will happen after many repeated trials. You've experienced probability when you've flipped a coin, rolled some dice, or looked at a weather forecast. Go deeper with your understanding of probability as you learn about theoretical, experimental, and compound probability, and investigate permutations, combinations, and more!
