There's only a few points here. The points only go up to here. This is if I take 0 steps left, 1 step left, 2 steps left, 3 steps left, 4 steps left, and then I plot it. And then I say, what's the probability using the binomial distribution? And then this is my final position. If I take 0 steps to the left, then I take 4 steps to the right, so my final position is at 4. So that's this scenario right here.
