Now if you were to, if you have much more than five cases here, if instead of saying that the number of heads for flipping a coin five times, you said x is equal to the number of heads of flipping a coin five million times, then you can imagine you'd have much, much, you know, the bars would get narrower and narrower relative to the whole hump. And what it would start to do, it would start to approach something that looks really, something that looks really like a bell curve. Let me do that in a color that you can see better that I haven't used yet. So it would start to look, so if you had more and more of these, if you had more and more of these possibilities, it's going to start approaching what looks like a bell curve. And you've probably heard the notion of a bell curve. And the bell curve is a normal distribution. So if you, one way to think about it is the normal distribution is a probability density function.
