Objectives of studying the discipline |
To create a knowledge base and skills for students in the field of probability theory and mathematical statistics acquaint students with the basic principles of probability theory and examples of their applications further formation of students’ skills in abstract mathematical thinking and the ability to apply it in specific tasks, enhancing their mathematical culture As a result of the study, the student should be able to: be able to: use the basic laws of random phenomena; apply methods of probability theory and mathematical statistics in other sciences; |

Teaching Methods |
interactive methods of teaching (working in small groups (team), problem training) are organized taking into account the inclusion in the learning process of all students of the group. Joint activity means that each student makes his own individual contribution, in the course of the work there is an exchange of knowledge, ideas, methods of activity. Organized individual, steam and group work. Interactive methods are based on the principles of interaction, activity of trainees, reliance on group experience, mandatory feedback |
