====== Probability theory====== Quite often in life we do not know for sure, what will be the result of an experiment or a process. For example, some hacker tries to attacks a particular information system. {{:probability:hakker.png|}} Surely both, the attacker and the information system owner wants to know the risks. So how to describe, what is going to happen? The answer to this gives probability theory.\\ \\ [[probability:01_event_probability]]\\ [[probability:02_multiple_event_probability]]\\ [[probability:03_conditional_probability]]\\ [[probability:04_total_probability]]\\ [[probability:05_expected_value]]\\ [[probability:06_inequalities]]\\ [[probability:07_game_notation]]\\
