I would really appreciate a fast answer

Are you really serious? You want us to the problem for you? On top of that you want it fast. The title of the website is not free math solutions but rather free math help. It is like a game, you submit a problem that you can't do, show the work that you tried to solve the problem and then some tutor will guide you to the correct solution. It really is fun and I truly hope that you give it a try.

I'll even give you a hint. Suppose the four people are A, B, C and D, and the 4 pieces are called w, x, y and z. What might a listing of what the 4 people have look like. If you know what the form of what something should like you might be able to count all the combination.

Consider A has w from A (Aw), Bx, Cx, Dz and B has .... and C has and D has ..... This will yield just one result.
