In a deterministic universe, based on Newtonian concepts, there would be no probability if all conditions were known (Laplace's demon), (but there are situations in which sensitivity to initial condit ...
Consider an experiment that can produce a number of results. The collection of all results is called the sample space of the experiment. The power set of the sample space is formed by considering all ...
Probability theory is applied in everyday life in risk assessment and in trade on financial markets. Governments apply probabilistic methods in environmental regulation, where it is called pathway ana ...
Main article: Probability theoryLike other theories, the theory of probability is a representation of probabilistic concepts in formal terms—that is, in terms that can be considered separately from t ...
Main article: History of probabilityThe scientific study of probability is a modern development. Gambling shows that there has been an interest in quantifying the ideas of probability for millennia, b ...
The word Probability derives from the Latin probabilitas, which can also mean probity, a measure of the authority of a witness in a legal case in Europe, and often correlated with the witness's nobili ...
Main article: Probability interpretationsWhen dealing with experiments that are random and well-defined in a purely theoretical setting (like tossing a fair coin), probabilities describe the statistic ...
