Math Problem Statement
(B ∩ C)′.
Solution
The expression represents the complement of the intersection of sets and .
Understanding the Expression
-
Intersection: is the set of all elements that are common to both sets and .
-
Complement: The complement of a set, denoted by a prime (), consists of all elements that are not in that set, relative to a universal set .
Applying These Definitions
- Step 1: Find the intersection .
- Step 2: Determine the complement , which includes all elements in the universal set that are not in .
Alternative Representation Using De Morgan's Laws
By De Morgan's Law:
This means that the complement of the intersection of and is the union of their individual complements.
Conclusion
- includes all elements that are in (not in ) or in (not in ).
