The given information is:

Number of boys =12

Number of teams =2

Number of boys to each team =6

Pick first 6 boys from 12 boys, 

Total no. of ways of choosing is:

\frac{12 !}{(12-6) ! 6 !}=\frac{12 !}{6 ! 6 !}=924

Pick last 6 boys from 6 boys and the number of ways this can be done is 1 .

Since the two groups are similar, there is no differentiation between them. Therefore, we need to divide it with 2 !=2 .

The total numbers of ways:

\frac{924}{2}=462
