perplexus.info :: Probability : Fateful Fickle Fifteen

Fateful Fickle Fifteen (Posted on 2005-03-24)

There is a bag with balls numbered 1 to 9. Two players take turns at randomly taking a ball from the bag. If a player gets three balls that sum fifteen, he wins. Getting fifteen with more or less balls doesn't count.

What are the odds of the first player winning? Of a draw?
