WebWhen events are independent, we can use the multiplication rule, which states that the two events A and B are independent if the occurrence of one event does not change the probability of the other event. P (A∩B) formula can be written as P (A∩B) = P (A) × P (B). P (A∩B) formula is given as: P (A∩B) Formula P (A∩B) = P (A) × P (B) where, WebMy academic and professional background and pursuits are quite eclectic.

WebIf A and B are independent events, then the events A and B’ are also independent. Proof: The events A and B are independent, so, P (A ∩ B) = P (A) P (B). From the Venn diagram, we see that the events A ∩ B and A ∩ B’ are mutually exclusive and together they form the event A. A = ( A ∩ B) ∪ (A ∩ B’). Also, P (A) = P [ (A ∩ B) ∪ (A ∩ B’)].
