Opa distributes 12 coins of 1 euro between his three grandchildren. Jan must receive at least 4 euros, Els and Piet must each receive at least 3 euros. Piet may receive a maximum of 4 euros. In how many ways can the money be distributed?
You could just make a chart:
J E P
4 4 4
4 5 3
5 4 3
5 3 4
6 3 3
Can you think of any other ways to meet all 3 conditions?
