# Probability theory

## Overall Course Objectives

To provide the participants with an intuitive and rigorous understanding of probabilistic concepts. The course will familiarize the student with different sources of variability that occur in technical fields and science. This is partly done by exposure to a number of basic models of widespread application. Introduction of various standard techniques enables the students to perform calculations of probabilistic nature. The course provides the mathematical background for probabilistic methods used in statistics courses as well as courses within technical areas with a significant component of random phenomenona. Examples are models of reliability, formation of queues, traffic, analysis of signals, DNA-sequence modeling, etc.
