Learning outcomes
By the end of the course module the student should know the basic tools of probability calculus, with a special focus on their role in the statistical analysis. In particular, the student should be able to: - compute the probability of events, by using the axioms and the fundamental theorems of probability calculus - identify the main discrete and continuous random variables and compute their expected values and variances - analytically treat univariate and bivarate random variables.
Course contents
Events and probability: probability spaces, conditional
probabilities, Bayes theorem.
Discrete random variables: probability mass functions,
examples of random variables, expectation and variance, bivariate
discrete distributions.
Independence of random variables, sums of random variables,
indicator functions.
Continuous random variables: density and distribution
functions, examples of continuous random variables, expectation and
variance. The Gaussian distribution and properties.
Functions of discrete and continous random variables.

Assessment methods
The learning assessment is composed by a written test lasting 2 hours, followed by an oral examination. The written test is aimed at assessing the student's ability to use the definitions, properties and theorems of probability theory in solving theoretical exercises. During the written exam, students can make use of a formulary and a calculator. The written test consists of some exercises articulated in several points with a final grade out of thirty.
