WebIf you run across a problem where you cannot reuse the numbers, here's what you'd do. You would have 10 numbers for the 1st slot, but only 9 for the second (since you used one of them in the first slot), then 8 for the 3rd, etc. To solve a problem like this, do the same thing: (10-9-8-7) And multiply together. Future problem solved!
WebSo, the permutations have 6 times as many possibilites. In fact there is an easy way to work out how many ways "1 2 3" could be placed in order, and we have already talked about it.
