@jmw150 you do mean these spaces? https://en.m.wikipedia.org/wiki/Probability_space
feels definitively less crazy than the random formulae you have in school involving factorials etc. may be due to sets being commonly used to describe algorithms in computer science (also explains why i have no problem with most theorethical cs but with many math topics if they are in classic notation ;)
@bonifartius Wish I did.
Because of the money the stats doctrine makes, really only graduate school stat and math books get into the meat of it.
