This is not homework - it's just maths for a hobbygame I'm thinking about.
I have 3 groups of 5 elements - let's call them A B C D E, M N O P Q, and V W X Y Z.
If a given entity is assigned one from each group, e.g. AMV or ANW, or even CYV - how many possible entities are there?
This is assuming, by the way, that AMV and VMA are distinct from each other. Order matters.
I think it's a huge amount - 625 maybe? But I'm not sure.
Can someone help me out please? Thanks.
I figure I could take a bear.
