So the total number of combinations would be (2^10) - 1; because if one girl has to be sent, then she cannot send zero people...hence the minus 1. Then I think I would subtract all combinations that included only boys...correct???

So I am not sure if this is correct, but would 2^10 - 2^6 -1, or 959 combinations be correct?
