Question

jason wants to choose 9 players for his track team ,there are 12 players to choose from.how many different teams can jason make?

Answer 1

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 2

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`

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

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

`=(1320)/(6)=220`

Thus, 220 team can Jason make.
