Joint Probability Distribution

Given a set of random variables X1 ... Xn, an atomic event is an assignment of a particular value to each Xi.

The joint probability distribution is a table that assigns a probability to each atomic event. Any question of conditional probability can be answered from the joint.[Example from Russell & Norvig.]
