That is a good question. That is what occurs with the license plates that for each spot you can have any of the 26 letters each time.
In the example with permutations it is because, imagine there are 3 pieces of paper, each one has a letter (a,b, or c). Thus when first reaching in a bag of these letters, there are 3 to choose from. The second time, there are only two letters left. The third time there is only one letter left.
So your question is a different problem, but it's also a good one.
In permutations why can not the letters be repeated in each set to bring about even more permutations?i.e.instead of just a/b/c~b/a/c~ why could there not be a/a/b/c~b/a/b/c/b/a/b/ etc.
couldnt watch this.. way too much noise in the background and it was too annoying
