Scientific Foundation of Marginal Probability
Marginal probability is defined by the formula P(A) = P(A and B) + P(A and not B), where P(A) is the probability of event A, P(A and B) is the joint probability of events A and B, and P(A and not B) is the joint probability of A occurring and B not occurring. This formula, derived from the axioms of probability, is a cornerstone of probability theory and is widely accepted in peer-reviewed statistical literature. The Marginal Probability Calculator uses this formula to ensure accurate results for analyzing event probabilities in various applications.
