Evidence under Bayes' Theorem Law and Legal Definition

The evidence under Bayes' Theorem refers to a theory of evidence which concerns the probability of an event and it's inverse. It is based on inverse probably principle. The theory compares the probability of finding particular evidence when the accused were guilty and when s/he is not guilty.

The Bayes' theorem was discussed in Rhodes v. Cracker Barrel Old Country Store, Inc., 213 F.R.D. 619, 658 (D. Ga. 2003). The court held that it is a conditional probabilities theorem. The theory states the probability that “an event A occurs given that another event B already has occurred is equal to the probability that the event B occurs given that A already has occurred, multiplied by the probability of occurrence of event A and divided by the probability of event B.”
