**Reiny**, Saturday, March 1, 2008 at 4:38pm"odds" do not have the same meaning as probability

in general the odds in favour of an event is the ratio of the probability of that event happening to the probability of the event not happening.

so you were partly right, the**probability**of 4 cosecutive tails is 1/15

so the prob. of not getting 4 consecutive tails is 15/16

and the odds in favour of 4 consecutive tails is 1/16:15/16

= 1:15
