Wow, this one was kind of tricky. Why is there only one possibility?
As I understood so far, there must be at least 4 girls in the group. So only the 4 girls is one possible combination. Than we have all the other combinations with the boys included, 1 at a time, only 2 of them, and finally all 3.

( B, B , B ) & ( G , G , G , G )

Since the team must include all the girls , we must include all the girls and we can have only 1 team...
