Full solution stays hidden until you ask for it.
1. Identify the shared joint count or probability.
2. Divide by B total for P(A|B).
3. Divide by A total for P(B|A) and compare.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Assuming P(A|B)=P(B|A) without checking totals.
