L2 : Some Basic Propositional Logic

In this lecture, we equip ourselves with the basics of propositional logic required for probability theory.

In particular, we look at the logical expressions 'not', 'and', and 'or'; learning to translate between English and propositional logic; get acquainted with truth tables; and proceed to use truth tables to identify valid inferences along with tautological, contradictory, and contingent propositions.
