Inclusion exclusion proof

WebProof: P(A ∪ B) = P(A ∪ (B \ A)) (set theory) = P(A) + P(B \ A) (mut. excl., so Axiom 3) = P(A) + P(B \ A) + P(A ∩ B) – P(A ∩ B) (Adding 0 = P(A ∩ B) – P(A ∩ B) ) The Inclusion … The inclusion exclusion principle forms the basis of algorithms for a number of NP-hard graph partitioning problems, such as graph coloring.
