Keltham now continues upon his project of making random diving runs on Probability from random angles in hopes of conveying a fragmentary understanding to adults over days instead of a true understanding to children over years.
He starts by posing a bunch of mostly-algebraic problems for deriving various conditional probabilities from others, what other places might call sheer math homework. Yes, he knows that he's using unknown dath ilani places and people and objects and statistics, and that he might as well be using gibberish words instead. He just doesn't know enough about Golarion to make up 12 realistic Golarion statistical problems, so just treat everything as algebra, please, and bear with the awfulness.
Likelihood ratio on ~~~ between ~~ and ~~~~ is 4, if P(~~◁~~~) = 68%, what was P(~~~~◁~~~)?
(It's pretty tame awfulness by comparison to math homework in almost any Chelish math class. The main awful thing about it is how Keltham doesn't work any similar example problems before expecting you to solve the ones he poses. The other awful thing is that Keltham sometimes makes mistakes in his own math, and when that happens he expects you to argue with him when he gives you the wrong answer.)
