Let's analyze the given Venn Diagram and solve the questions:

4. $A \cap B$ (Intersection of A and B)

The intersection $A \cap B$ contains elements that are in both sets $A$ and $B$. From the diagram, the overlapping region of $A$ and $B$ includes the element:

• $\{3\}$

So, $A \cap B = \{3\}$.

5. $A \cup B$ (Union of A and B)

The union $A \cup B$ contains all elements in either $A$ or $B$ or both. From the diagram, $A \cup B$ includes:

• Elements in $A$: $\{2, 3, 11\}$
• Elements in $B$: $\{3, 5, 7\}$

Combining and removing duplicates:

• $A \cup B = \{2, 3, 5, 7, 11\}$

Final Answers:

4. $A \cap B = \{3\}$
5. $A \cup B = \{2, 3, 5, 7, 11\}$

Would you like detailed explanations or further examples of these concepts?

Here are 5 related questions to expand your understanding:

1. What is the difference between $A \cap B$ and $A \cup B$?
2. If set $U$ represents the universal set, what are the elements of $A^c$, the complement of $A$?
3. How would you represent $B^c$, the complement of $B$, using this diagram?
4. Can you identify which elements belong exclusively to $A$ but not $B$?
5. What would the set $A \Delta B$ (symmetric difference) look like?

Tip: Always double-check the Venn Diagram regions to correctly categorize elements in set operations!
