It's just like that. And just to give you the preview, it looks like this. The probability of getting any x, and it's a class of probability distribution functions. Just like the binomial distribution is and the Poisson distribution is, based on a bunch of parameters. But it's equal to, and this is how you would traditionally see it written in a lot of textbooks. And if we have time, I'd like to rearrange the algebra, just so you get a little bit more intuition of how it all works out. Or maybe we could get some insights on where it all came from.
