Once we use something up, then for each of those possibilities, we'll have one less for the next bucket. And so I could do 24 times 25 times 26, but just so I don't fully confuse you, I'll go back to what I have been doing. 26 possibilities for the leftmost one. For each of those, you would have 25 possibilities for the next one that you're going to try to figure out because you've already used one letter and they have to be different. And then for the last bucket, you're going to have 24 possibilities. So this is going to be 26 times 25 times 24, whatever that happens to be. And if we wanted to write it in the notation of permutations, we would say that this is equal to, we're taking 26 things, sorry, not 2p, 20, my brain is malfunctioning, 26, we're figuring out how many permutations are there for putting 26 different things into three different spaces.
