The Venn Diagram shows two events, A and B, with four regions labeled I, II, III, and IV.
Step 2: Determine the regions that make up \( A' \)
\( A' \) represents the complement of event A, which includes all regions that are not part of event A. In the Venn Diagram, event A includes regions I and II. Therefore, \( A' \) includes regions III and IV.
Step 3: Verify the correct answer
From the options provided, the correct answer is the one that includes regions III and IV.
