**Aims:**

The aims of this course are

- To develop the tools of probability theory with a view to applications in statistical inference and actuarial science
- To provide an introduction to computer simulation in R and its applictions to probability and statistics.

**Summary:**

In this course we develop probability models for random phenomena. In particular, we develop the methodology needed for the study of random variables and their distributions. Random variables are essential to the modelling of most random phenomena, and have applications in statistical science, financial mathematics, and actuarial science. Common discrete and continuous random variables (Bernoulli, binomial, geometric, hypergeometric, Poisson, uniform, normal, exponential, gamma) which are frequently used for modelling are introduced and their properties investigated. We also introduce multivariate distributions, conditional distributions, and criteria for independence of random variables. We study sums of independent random variables, and introduce the weak law of large numbers and the central limit theorem.

We will use computer simulation as an aid to understanding the behaviour of probabilistic and statistical models, and to doing calculations for these models.
