A World Series is decided by a best-of-seven series, so the first team to win four games wins the championship. In practice, that means a maximum of seven games can be played, but if a team reaches four wins earlier, the series ends immediately. Key points:
- Maximum games: 7
- Minimum games needed to win: 4
- Typical range: 4 to 7 games, depending on how quickly one team reaches four wins
If you’d like, I can explain how the expected number of games is calculated under different win probabilities per game (for example, assuming each game is fair with a 50% chance for either team), or tailor the explanation to a specific hypothetical scenario.
