Any of 10 horses can be first, giving 10 possible options.


Any of remaining 9 horses can be second, giving 9 other possible options.


Any of remaining 8 horses can be third, giving 8 other possible options.


Thus the total number of different possible options is 10*9*8 = 720.    ANSWER

Solved.
