Scientific Foundation of Joint Probability
Joint probability is defined by the formula P(A and B) = P(A) * P(B) for independent events, or P(A and B) = P(A) * P(B|A) for dependent events, where P(A and B) is the probability of both events A and B occurring, P(A) and P(B) are the individual probabilities, and P(B|A) is the conditional probability of B given A. These formulas, fundamental to probability theory, are derived from the axioms of probability and are widely accepted in peer-reviewed statistical literature. The Joint Probability Calculator uses these formulas to ensure accurate results for analyzing event combinations.
