This is a .48 empirical probability, which is significantly larger than the .3125 probabillity you would compute of going to game 7 if the teams are evenly matched (e.g. every game is a fair coin flip). The article goes on to describe possible explanations of this discrepancy, including home-field advantage and baseball strategy.   [e]edit: corrected a typo[/e]   « Last Edit: Oct 26th, 2003, 4:26am by william wu » IP Logged [ wu ] : http://wuriddles.com / http://forums.wuriddles.com towr wu::riddles Moderator Uberpuzzler Some people are average, some are just mean.     Gender: Posts: 13730 Re: 7-Game World Series Statistics   « Reply #1 on: Oct 24th, 2003, 1:53am » Quote Modify on Oct 24th, 2003, 12:40am, william wu wrote: 35 of the 94 world series since 1905 have gone to game 7. This is a .48 empirical probability I think that should be 0.372 , not .48 (which is allmost half, not just over a third) It's not surprising it doesn't behave like a coin toss though.. (they wouldn't have to bother playing if it were just chance..)

However, the ratio of all world series since 1905 that have gone to game 7 is .372.
