**Diagram Explanation:**

- **Venn Diagram:** A Venn diagram is displayed with three intersecting circles labeled \(A\), \(B\), and \(C\), within a universal set \(U\). The numbers in various regions represent the number of elements shared between or exclusive to the sets.

  - In the left circle (A): \(4\)
  - In the intersection of A and B: \(3\)
  - In the intersection of B and C: \(7\)
  - In the intersection of A and C: \(5\)
  - In the intersection of all three sets A, B, and C: \(2\)
  - Exclusive to B: \(8\)
  - Exclusive to C: \(15\)
  - Outside all three circles but within the universal set: \(10\)
