For any two sets A and B, the complement (A union B)' is equal to which of the following?
- A' intersect B'
- U minus (A union B)
- ((A minus B) union (B minus A))'
- A' intersect (U minus B)
Correct answer: A' intersect B'
Solution
By De Morgan's Law, the complement of a union equals the intersection of the complements: (A union B)' = A' intersect B'.
