@.WhiteDragon.
I'm pretty sure it would be B. but it depends on what your lesson is about.
permutations
8 possible options for first place, 7 possible for second place, and 6 possible for third 8×7×6=336 possible ways.
thanx punksauce and ddcamp I got 100%
Or using the combu formula: n=8 (total runners) r=3 (people getting medals) \[nPr = \frac{n!}{(n-r)!}=\frac{8\times7\times6\times5...}{6\times5\times4...} = \frac{6\times7\times6}{1}=336\]
