probability
A number from 0 to 1 (or 0% to 100%) that describes how likely an event is to occur.
Probability is the measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 represents that the event is impossible, and 1 represents that the event is certain to occur. For example, the probability of getting heads when flipping a coin is 0.5 or 50%.
Probability can be calculated by dividing the number of favorable outcomes by the number of possible outcomes. For instance, if a fair six-sided die is rolled, the probability of getting a 6 is 1/6 or approximately 0.166.
There are two types of probability: theoretical and empirical. Theoretical probability is calculated based on the assumption that all outcomes are equally likely, while empirical probability is calculated by conducting experiments and collecting data to determine the frequency of occurrence of an event.
Probability plays a crucial role in many fields, including statistics, finance, science, engineering, and more. It helps in decision-making processes and risk assessment, and provides a systematic approach to analyze and solve problems.
