Fundamentals of Probability Theory
This page introduces core concepts in probability theory, focusing on counting principles and types of events. It covers the multiplication rule, permutations, variations, and random events.
The multiplication rule is explained as a method to calculate the total number of ways to make a series of choices.
Definition: Permutations are defined as sequences created from all elements of a set, calculated using the formula n! = 1 · 2 · 3 · ... · n.
Variations are presented in two forms: without repetition and with repetition. The page also defines random events as subsets of the sample space.
Highlight: The page emphasizes important concepts such as impossible events emptyset and mutually exclusive events A∩B=Ø.
The notion of complementary events is introduced, with the relationship between an event and its complement explained using set notation.
