how many combination of players can a coach have if he needs to pick 2 out of a total of 4
Answer: 6 combinations.
Step-by-step explanation:
Given :- Total number of players= 4
Then, combination of players can a coach have if he needs to pick 2 out of total players=\(^4C_2=\frac{4!}{2!2!}\)
\(=\frac{4\times3\times2\times1}{2\times2}\)
\(=6\)
Therefore, there are 6 combinations of players can a coach have if he needs to pick 2 out of total players of 4.
There are 6 combinations of players can a coach have if he needs to pick 2 out of the total players 4.
We have given that,
6 combinations.
Total number of players= 4
We have to determine what combination of players can a coach have if he needs to pick 2 out of the total players,
\(_n C_r=\frac{n !}{r ! (n-r) !}\\_n C_r = \ number \ of \ combinations\ = \ total \ number \ of \ objects\ in \ the \ set\\r = \ number \ of \ choosing \ objects \from \ the \ set\)
\(C(4,2)=\frac{4!}{2!2!}\)
\(C(4,2)=6\)
Therefore, there are 6 combinations of players can a coach have if he needs to pick 2 out of the total players 4.
