"Actually, now that I think about it, the reason I know a key constant here is that the wizard who teleported me to Cheliax from the Worldwound seemed to know it? In particular, he knew what I was talking about when I asked about the square root of the average squared difference from the average over Intelligence. There's no reason he'd have known that for Intelligence unless this particular concept was already known in Golarion. Which means that, in fact, somebody somewhere in Cheliax knows substantially more math about Probability than this class has ever heard of existing."
"I shall endeavor not to be distracted by trying to figure out how this could possibly be true, and try to teach the basic layers of Probability from a dath ilani perspective instead, but, somebody should actually let me know if I'm improvising something more poorly than existing books teach it. You in particular, Isidre, I know you're reading the transcript on this."
