### Learning Outcomes

The course’s material includes mathematical definitions, fundamental concepts, results and reasoning methodologies that pertain to basic Probability Theory objects and models underlying the foundations and applications of computer science. Moreover the relevant connections of probability theory to several more specific branches of computer science are presented. The course directly supports most of the curriculum subjects and lessons: Note that during the lesson, specific examples of application are discussed in some of the above curricular subjects such as applications in telecommunication systems, cryptography, digital services such as e- learning, e-health using new technologies with the help of programs such as Matlab, Octave, SPSS and R.

Upon successfully completion of the course the students will be in position to:·

• Know, describe the basic knowledge of Probability Theory (indicatively: probability definition, combinatorial analysis, random variables, discrete and continuous distributions, two-dimensional probabilistic generators and generators, etc.) basic values and the basic tools (probability mass and density functions, etc.) of Probability Theory.·
• Calculate the probabilities of possible non-trivial probability problems using probability theory, combinatorial and calculus.·
• Identify and know well-known probabilistic models in Computer Science problems.·
• Choose the appropriate mathematical method so that it can model the problem that it is called upon to solve and compile new probabilistic models for problems and systems that appear in computer science using simpler probabilistic models.·
• Know, handle, and understand Matlab, Octave, SPSS, and R programs on probability theory applications in computer science.
