For use to be able to determine how many ways can first, second, and third place be awarded to 3 contestants, we will be using the permutation formula.


\text{ nPr = }\frac{n!}{(n\text{ - r)!}}

Where,

P = the number of permutations

n = total number of objects in the set = 3 contestants = 3

r = number of choosing objects from the set = 1st, 2nd & 3rd place = 3

We get,


\text{ nPr = }\frac{n!}{(n\text{ - r)!}}
\text{ }_3P_3\text{ = }(3!)/((3-3)!)
\text{= }\frac{3\text{!}}{0!}\text{ = }\frac{\text{ 3 x 2 x 1}}{1}
\text{ = }\frac{\text{6}}{1}\text{ = 6}

Therefore, there are 6 possible ways can first, second and third place be awarded to 3 contestants.

The answer is 6.
