WebInclusion-Exclusion Principle. Let A, B be any two finite sets. Then n (A ∪ B) = n (A) + n (B) - n (A ∩ B) Here "include" n (A) and n (B) and we "exclude" n (A ∩ B) Example 1: Suppose A, B, C are finite sets. Then A ∪ B ∪ C is finite and n (A ∪ B ∪ C) = n(A) + n(B) + n(C) - n(A ∩ B) - n(A ∩ C) - n(B ∩ C) + n(A ∩ B ∩ C ... WebCodeforces.
