# Lab: Inference
## Problem 1: Working Out the Theory
Because Pr(X) is the same on both sides, it can be factored out of the proportions. The result of the calculations is the same either way.
## Problem 2: Independence and Computation
go to class: 3/5
given go to class:
early: 3/6
partied: 3/6
test: 3/6
hungry: 2/3
(early, no, no, yes) = 1/20
(late, no, no, no) = 1/40
(late, yes, yes, yes) = 1/20
(late, no, yes, no) = 1/40
