You can put this solution on YOUR website!
If we start by selecting and setting aside what the third and fourth children will receive,
we have 7 choices for our first pick (to be set into a bag labeled for child # 4),
and then we have 6 choices for our second pick (to be reserved for child # 3.
After that, we have 7-1-1=5 balloons left.
There are 5%2A4%2F2=10 different ways to pick the 2 balloons to be given to child # 2.
Our choices multiply, so we had
7%2A6%2A10=highlight%28420%29 different ways to decide who gets what balloon or what set of balloons.
