You can put this solution on YOUR website! .
10*9*8 ways.
You can choose the first winner by 10 ways;
then you can choose the second winner by 9 ways among remaining 9 people.
Finally, you can choose the third winner by 8 ways anong remaining 8 people.
It gives you the final answer 10*9*8 ways.
It is a STANDARD way to solve such problems.
