He could only make one team, considering that if you do 12-9, you are left with 3, and Jason wants to have his team consisted of 9 players. However, if you make 3 teams with 4 players on each team, or 4 teams with 3 players on each team, you could do that as well.

Answer: 220 team can Jason make.

Explanation:

Since, the total numbers of players = 12

The number of players in one team = 9,

Hence, the total combination of choosing 9 players out of 12 players


=^12C_9


=\frac{12!}{9!* (12-9)!


=(12* 11* 10* 9!)/(9!* 3!)


=(12* 11* 10)/(3* 2)


=(1320)/(6)=220

Thus, 220 team can Jason make.
