Math Problem Statement

Show the following sets using Venn diagrams: 1. (A ∩ B)' ∩ C 2. (A ∩ B) ∪ (A' ∩ B')

Solution

The problem asks to represent the following set operations using Venn diagrams:

  1. (AB)C(A \cap B)' \cap C
  2. (AB)(AB)(A \cap B) \cup (A' \cap B')

Let's break down each set expression before illustrating how to represent them in a Venn diagram:

1. (AB)C(A \cap B)' \cap C

  • ABA \cap B is the intersection of sets AA and BB, which means the elements common to both AA and BB.
  • (AB)(A \cap B)' is the complement of ABA \cap B, meaning everything outside the intersection of AA and BB.
  • The final expression (AB)C(A \cap B)' \cap C represents the elements that are in CC but not in the intersection of AA and BB.

2. (AB)(AB)(A \cap B) \cup (A' \cap B')

  • ABA \cap B is the intersection of AA and BB.
  • ABA' \cap B' represents the intersection of the complements of AA and BB, i.e., the elements that are outside both AA and BB.
  • The union (AB)(AB)(A \cap B) \cup (A' \cap B') includes all elements either in the intersection of AA and BB or outside both AA and BB.

Would you like me to generate the Venn diagrams for these expressions?
