Full solution stays hidden until you ask for it.
1. Define fair model probabilities.
2. Simulate many trials matching sample size.
3. Compare observed result to simulated distribution.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Concluding unfair solely because observed does not equal expected exactly.
