Question

Could it be solved by the branching method that are taught in school instead of model?

Thanks

Answer

A model isn’t needed but the branching method isn’t the best method here since the boys and girls are distinct. Simply identifying that both the boys and girls have 5 units at the start, with a total of 10 units, is enough to solve.
