5/2 -- Group B: Introduction to Probability (Tim Austin)

This is the first in a series of 2 meetings. Mathematical probability emerged from the study of gambling, statistics, and the observed outcomes of experiments that are subject to some ‘random’ external in- fluences. Here we will introduce some of its basic concepts: 1. Sample space and events; 2. Probability functions; 3. Random variables and expectation.
