Question 1146533
It sounds like the order that the top 3 finish matters, so
if the top 3 are 7, 19, 21, then the possible orders are:
7, 19, 21
7, 21, 19
19, 7, 21
19, 21, 7
21, 7, 19
21, 19, 7
--------------
So, you want the number of permutations , 22 things
taken 3 at a time:
{{{ n! / ( n - r )! }}}
{{{ n = 22 }}}
{{{ r = 3 }}}
{{{ 22! / ( 22 - 3 )! }}}
{{{ 22! / 19! = 22*21*20 }}}
{{{ 22! / 19! = 9240 }}}
