So this right here, I wanted to say, what does the normal distribution tell me is the probability of ending up with exactly 0 left steps. And then this is a little bit tricky because the binomial distribution is a discrete probability distribution. You could just look at this chart or look here and you say, what is the probability of having exactly, let's say, 1 left step and 3 right steps, which puts me right here. Well, you just look at this chart and you say, oh, that puts me right there. I just read that probability. It's actually 0.25. And I say, oh, I have a 25% chance of ending up 2 steps to the right.
