A Philosophical Essay on Probabilities

Pierre-Simon Laplace

"A Philosophical Essay on Probabilities" is the work by award winning mathematician Pierre-Simon Laplace on the mathematical theory of probability. Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. Probability theory is used widely in areas of study such as statistics, mathematics, science, finance, gambling, artificial intelligence, machine learning, computer science, game theory, and philosophy to, for example, draw inferences about the expected frequency of events. Laplace's book consists of two parts under the headings, "A Philosophical Essay on Probabilities" and, "Application of the Calculus of Probabilities."
