Answer:

120 possibilities.

Step-by-step explanation:

The number of teammates = 6

They are competing for the top three positions which are first, second and third.

Any of the 6 teammates can achieve the first position. Hence, three are total 6 possibilities for the first position.

Now, 1 teammate is already achieved the first position. Hence, there are 5 possibilities for the second position.

Similarly, 2 teammates is already achieved the first and second positions. Hence, there are 4 possibilities for the third position.

Therefore, there are 6×5×4 = 120 possibilities.
