Probability and Statistics

• 26 hrs lectures
• 26 hrs exercises

• 70 pts final exam (written part)
• 30 pts numeric exercises

Acquired knowledge can be applied, for example, in other courses or in the BSc/MSc thesis.

The main goal of the course is to introduce basic principles and methods of probability and mathematical statistics which are useful not only in computer sciences.

The world around us is complex and we try to describe it using mathematical models. However, not all the models are deterministic. In many situations, randomness plays an important role and some phenomena occur only with a certain probability. Students will learn about the probability, learn how to model the behaviour of random variables and analyze obtained (measured) data using selected methods of mathematical statistics. Overall, probability and related topics are important parts of computer science.
