# Discrete Probability

Bayes' Rule is used to re-express conditional probabilities

$P(A|B)$

.Probability spaces describe all of the possible values of a random variable, and how likely each of those outcomes are.

Two variables are equal if

$X(\omega) = Y(\omega)$

for all $\omega \in \Omega$

, where $\Omega$

is a probability space (all possible values).http://prob140.org/textbook/content/Chapter_03/03_Equality.html
