There's a couple ways of thinking about this problem.
00:03
One is that if you had these six boxes to try and make and you had the letter q, and i asked you just to put one, two, three, four, five, cue in one of those six boxes, you'd have six options to choose from.
00:21
But then as you move on to the next letter, you, so let's say you put a q right here, it doesn't really matter.
00:27
And i asked you to do how many options do you have for the letter u? well, now you'd have five options.
00:35
So let's say you put you here, and then your next one would be a, to put a anywhere, but you only have four options.
00:43
And, you know, i could keep saying that over and over in.
00:48
And what's important here is all the letters are different, you know, two and one...
