Math Problem Statement

(B ∩ C)′.

Solution

The expression (BC)(B \cap C)' represents the complement of the intersection of sets BB and CC.

Understanding the Expression

  1. Intersection: BCB \cap C is the set of all elements that are common to both sets BB and CC.

  2. 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 UU.

Applying These Definitions

  • Step 1: Find the intersection BCB \cap C.
  • Step 2: Determine the complement (BC)(B \cap C)', which includes all elements in the universal set UU that are not in BCB \cap C.

Alternative Representation Using De Morgan's Laws

By De Morgan's Law: (BC)=BC(B \cap C)' = B' \cup C'

This means that the complement of the intersection of BB and CC is the union of their individual complements.

Conclusion

  • (BC)(B \cap C)' includes all elements that are in BB' (not in BB) or in CC' (not in CC).
