Ordered permutation
WebFor permutations, the order matters. Suppose we need to know the number of possibilities for a four-digit lock. There are 10 possible values, and we’re picking 4. Statisticians state … WebAlright, so this is where permutations start to be useful. Although, I think a lot of things like this, it's always best to reason through than try to figure out if some formula applies to it. So in this situation, well, if we went in order, we could have 26 different letters for the first one, 26 different possibilities for the first one.
