So I made another, there's a convergence worksheet on this spreadsheet as well, if you click on the bottom tab on convergence. And I did, this is the same thing, but I just wanted to show you what happens at any given point. So let's say that I wanted to, let me explain this part, this spreadsheet to you. So this is, what's the probability of moving left, right, this is, so this is just saying, I'm just fixing a point, what's the probability, and you could change this, of my final position being 10. And then this essentially tells you that if I take 10 moves, then for my final position to be 10 to the right, I have to take 10 right moves and 0 left moves. That's a typo right there, it should be moves, not moves-ed. If I take 20 moves to end up 10 moves to the right, then I have to make 15 right moves and 5 left moves.
