Add a college Probability course!

I am currently taking college Probability and struggling a bit. Khan Academy helped me SO much with my calc 3 and linear algebra classes, and I was disappointed to learn that there was no probability course. You know, with moment generating functions, gamma distributions, and a bunch of other stuff that I was told by my AP stats teacher "wasn't important". (Sorry Mr Browning.) I know there's a probability section in the AP stats course, but what we're doing goes way beyond that. I would love to see Sal or Grant (or anyone else!) tackle this because I'm struggling a bit and I think others would benefit from it too.
