This is the first lecture of a short course introducing probability and statistics, meant for an advanced first year undergraduate class. The course will be about 8 lectures long, and will go from basic sets, counting, probability and odds, to probability measures, conditional probabilities, Bayes rule, random variables, probability distributions (discrete and continuous), mean, variance, Binomial, Poisson, normal distributions, and perhaps some words in the direction of the Central Limit Theorem. We will not discuss inference in this course, so it is a rather limited, specific introduction to the subject.
In this lecture I review some basic notation and terminology for sets, including operations and rules, the Inclusion/Exclusion principle and partitions; together with some basic facts about functions.

Probability and Statistics: an introduction

A brief introduction to Probability and Statistics. This short course will be aimed at advanced first year undergraduates, with good algebraic skills and some knowledge of calculus. We will discuss probabilities and odds, random variables, probability distributions (both discrete and continuous), for example the Binomial, Poisson and normal distributions, mean and variance and mention the Central Limit Theorem.
