The image shows a Venn diagram with three sets $A$, $B$, and $C$ along with their universal set $U$. The regions are numbered I to VIII, and we are tasked with identifying the region or regions corresponding to $A \cap B \cap C$, which represents the intersection of sets $A$, $B$, and $C$.

The region where all three sets overlap is the central region of the diagram, which is marked as V. Therefore, the region that corresponds to $A \cap B \cap C$ is:

• V (Region V)

Would you like more details or have any questions?

Here are five related questions to deepen your understanding:

1. What is the meaning of $A \cup B \cup C$ in this Venn diagram?
2. Which regions represent $A \cap B$, but not $C$?
3. Can you identify the regions representing only $C$ (i.e., $C - (A \cup B)$)?
4. What does $(A \cap B)^c$, the complement of $A \cap B$, correspond to in this diagram?
5. How would you represent $A^c \cup B^c \cup C^c$, the complement of all sets?

Tip: In Venn diagrams, the overlap of sets visually represents intersections.
