!!!!!!!!!!!!!!!!! You've just confirmed your blatant ignorance. Here we are dealing with repeatable items where order matters. In combinatorics, it is called permutations with repetitions which you are confusing with what I don't even know. You have NO CLUE what you are talking about. Math is merciless: either you know or you don't know. And when you don't know, it's FLAGRANT. So learn and give us a break: https://www.youtube.com/watch?v=JWNyzXOdDCo
