WebFeb 27, 2016 · Prove the general inclusion-exclusion rule via mathematical induction. "For any finite set A, N (A) denotes the number of elements in A." N(A ∪ B) = N(A) + N(B) − N(A ∩ B) and N(A ∪ B ∪ C) = N(A) + N(B) + N(C) − N(A ∩ B) − N(A ∩ C) − N(B ∩ C) + N(A ∩ B ∩ C). WebThe basis for proofs by induction is the exclusion clause of the inductive definition, the clause that says that nothing else is a so-and-so. Once the exclusion clause is made precise, as it is done in the Peano Axioms, we have the basis for proofs by induction. Consider the exclusion clause of arithmetic rewritten somewhat informally.
