In a Venn diagram, what is A' ∪ B' equal to?
Answer and explanation
Correct answer: (A ∩ B)'
De Morgan’s law states that the union of the complements of two sets equals the complement of their intersection: A' ∪ B' = (A ∩ B)'. An element belongs to the left side if it is outside A or outside B, which means it cannot be simultaneously inside both A and B. Therefore, option A is correct.
