The Dependent Probability Calculator determines the probability that two dependent events occur together. It uses the formula P(A∩B)=P(A)×P(B∣A)P(A ∩ B) = P(A) × P(B|A)P(A∩B)=P(A)×P(B∣A), where P(A)P(A)P(A) is the probability of the first event and P(B∣A)P(B|A)P(B∣A) is the probability of the second event occurring given that the first has already occurred. This concept is essential in understanding how one event can influence another in probability theory, such as drawing cards from a deck without replacement or selecting items from a limited group where outcomes affect each other.
