The formula P(A ∪ B) = P(A) + P(B) - P(A ∩ B) is known as the addition rule for probabilities. It is used to find the probability of the union of two events, accounting for the fact that the intersection of these events (the part that overlaps) should not be double-counted.

P( A ∪\cup∪ B )= P( A)+ P( B)- P( A ∩\cap∩

P( A $\cup$ B )= P( A)+ P( B)- P( A $\cap$
