CFA Level I
#1
  1. is it worth remembering? 2). Assuming so, how do I actually use it to update probability?
#2

just remember the joint probability and manipulate it, no need to remember bayes

#3

Is that short for Diapermula? I don’t know what that is, but Momma Bayes had quite enough of them by the time junior Bayes reached his first birthday.

#4

how?

#5

P(A|B) = P(AB)/P(B) = P(B|A)P(A)/P(B)
