There are $\displaystyle \binom {9}{3} = 84$ ways to choose three horses from nine.

There are $\displaystyle (3!) = 6$ ways for those three horses to finish in the top three places:

$\displaystyle \frac {6} {84} = \frac {1} {14} $.

That is hardly an impossible question. - Mar 8th 2008, 09:44 AMlorenzolama

i think theres more then 1/14 cause thats a lot of codes these are the codes if u choose 3 horses and they are not boxed yet. (Headbang)
