Probability theory is the branch of mathematics concerned with probabilityAlthough there are several different probability interpretations probability theory treats the concept in a rigorous mathematical manner by expressing it through a set of axiomsTypically these axioms formalise probability in terms of a probability space which assigns a measure taking values between 0. For any two events A and B ABc AcBc ABc AcBc Mnemonic. State the two basic laws of probability.

The tools of probability theory and of the related field of statistical inference are the keys for being able to analyze and make sense of data. 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 witnesss nobilityIn a sense this differs much from the modern meaning of probability which in contrast is a measure of the weight of empirical evidence and is arrived at from inductive reasoning and.
