someone posted an interesting problem from another board.(adsbygoogle = window.adsbygoogle || []).push({});

now, the upcoming world series have chicago playing & they haven't won it since 1918.

last year's winner, boston, hadn't won since 1917 !

the problem posed was:

"what are the odds of two teams (not specifically having to be boston/chicago ) winning titles in 1917 & 1918, then not winning another title between them until they go back-to-back again in 2004 & 2005."

apparently 16 teams present in 1917 - 1918 & with franchise expansion there are ~ 30.

he gave the answer ( which i am having trouble working out ), which i'll post as soon as we get a coupla ( or even 1 ! ) reply.

many thanks
