Because the normal distribution is so important. And actually, my 9-week-old son is watching, so this is the first time I have a live audience. But I thought he might pick up something about the normal distribution. But anyway, the blue line right here, and I'll trace it maybe in yellow just so you can see it, is the plot of the binomial distribution. And I connected the lines, but you see the binomial distribution look something more like this. Where this is the probability of getting to minus 4. This is the probability of going to minus 2.
