Conditional ProbabilitySuppose a card is removed from a pack of cards and kept aside.Let B be the event that the card is a spade. After this one card is drawn at random from the remaining 51 cards. Let A be the event that the second card is a spade. Under the assumption that B has happened n(A) = 12 P(A/B) = 12/51 It is read as probability of A when B has taken place or probability of A under B. P(A/B) = n(A Ç B ) / n(B) Multiplication Theorem of Probability
