It seems the image you provided isn't accessible to me. Could you please describe the problem in text form (e.g., the question, given data, or any diagrams mentioned)? That way, I can help you solve it step by step.

If you had a specific problem in mind (like a Venn diagram question, set theory problem, or another topic), sharing the details would allow me to assist effectively. For example, if it was about finding the number of elements in a union of sets, I could use the formula (n(A \cup B) = n(A) + n(B) - n(A \cap B)) once you provide the values of (n(A)), (n(B)), and (n(A \cap B)).

Let me know the problem details!
