Probability Theory

Probability theory is the study of reasoning with incomplete information. The laws of logic govern all correct reasoning when operating under conditions of perfect information. If$$A$$ is true, and if $$A$$ implies $$B$$, then we may deduce that $$B$$ is true as well. But in many cases, we may be uncertain about whether $$A$$ is true or not. Probability theory governs all correct reasoning when operating under conditions of incomplete or unreliable information. As such, it is an extremely useful field of study, with many applications.
