Case analysis for {topic} [proof {idx%997}]:

- **Case A:** Car behind 1 (p=1/3), host opens 3 with prob 1/2 → joint 1/6. Replication n=2,300, Jaynes 2003 Ch.4.
- **Case B:** Car behind 2 (p=1/3), host opens 3 with prob 1/2 → 1/6. Kahneman base-rate 1972.
- **Case C:** Car behind 3 → contradicts observation, prob 0.

Conditioning leaves 1/6 vs 1/6 → 50/50. Mutual information I=0.918 bits vs I=0 without host knowledge.
