Math Problem Statement

  1. Let 𝑈, 𝐴, and 𝐵 be nonempty sets such that 𝐴 ∩ 𝐵 is not empty. Draw a Venn diagram shading the region corresponding to (𝑨 ∩ 𝑩̅)

Solution

To represent the set ABA \cap \overline{B} using a Venn diagram, we need to follow these steps:

Understanding the Expression:

  • AA is a subset of the universal set UU.
  • BB is another subset of UU, which overlaps with AA because ABA \cap B \neq \emptyset.
  • B\overline{B} is the complement of BB, meaning all elements in the universal set UU that are not in BB.
  • The intersection ABA \cap \overline{B} represents the elements that are in AA but not in BB.

Venn Diagram Description:

  • Draw two overlapping circles within a rectangle representing the universal set UU.
  • Label one circle as AA and the other as BB.
  • ABA \cap \overline{B} corresponds to the part of circle AA that does not overlap with circle BB. This means you need to shade the region of AA that lies outside BB.

Would you like me to generate a visual representation of this Venn diagram?


Here are 5 related questions for further exploration:

  1. What does the region ABA \cap B represent on a Venn diagram?
  2. How would you represent ABA \cup B on the Venn diagram?
  3. What is the difference between ABA \cap B and ABA \cap \overline{B}?
  4. What happens if AA and BB are disjoint? How would ABA \cap \overline{B} look then?
  5. How do you represent AB\overline{A \cup B} on the diagram?

Tip: The complement of a set BB (denoted B\overline{B}) includes all elements that are outside of BB in the universal set.
