WebJul 6, 2024 · The distributive laws for propositional logic give rise to two similar rules in set theory. Let \(A, B,\) and \(C\) be any sets. Then \[A ∪ (B ∩ C) = (A ∪ B) ∩ (A ∪ C) \nonumber\] and \[A ∩ (B ∪ C) = (A ∩ B) ∪ (A ∩ C) \nonumber\] These rules are called the distributive laws for set theory. To verify the first of these laws ...
