Full solution stays hidden until you ask for it.
1. List paths leading to each final outcome.
2. Multiply probabilities along each path.
3. Add paths for each outcome and compare totals.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Judging each stage separately without checking final probabilities.
