#### Learning Outcome

After successful completion of the module
- Participants are familiar with important concepts of discrete and continuous probability spaces and stochastic processes and can in large part deduce them themselves
- master calculation rules for the determination and estimation of probabilities, expected values and variances,
- are able to map real problems to abstract probability spaces and
- can easily apply simple statistical tests.

#### Preconditions

IN0015 Discrete Structures, MA0901 Linear Algebra for Informatics, MA0902 Analysis for Informatics

### Courses, Learning and Teaching Methods and Literature

#### Learning and Teaching Methods

The module consists of lectures and tutorials. During the lectures students are asked to solve small exercises online. Students also receive weekly assignments, whose solution is discussed in the tutorials.

#### Media

Slide show, blackboard, written assignments.

### Module Exam

#### Description of exams and course work

Students will be assessed by a 120 minutes written exam, which consists of three types of exercises. Comprehension exercises test if the student understands the basic concepts and theorems of the lecture. They require students to apply these concepts to examples. Algorithmic exercises test if the student knows and is able to apply the presented rules to selected inputs. Modelling exercises test the ability of the student to use the mathematical tools from the lectures to model and solve concrete problems.

#### Exam Repetition

The exam may be repeated at the end of the semester.

#### Current exam dates

Currently TUMonline lists the following exam dates. In addition to the general information above please refer to the current information given during the course.
