Key Concepts in Axiomatic Probability
Sample Space (Ω): Axiomatic probability begins with the concept of a sample space, denoted by Ω. The sample space represents the set of all possible outcomes of a random experiment.
For example, if you’re rolling a six-sided die, Ω would be {1, 2, 3, 4, 5, 6}.
Event: An event is a subset of the sample space Ω. It represents a specific outcome or a collection of outcomes of the random experiment. Events are denoted by capital letters, such as A, B, or C.
Tossing two dice: We have
S = {1,2,3,4,5,6}2
Event: We define
E =(Sum of dice is equal to 7)
Axiomatic Probability in R
Axiomatic probability, also known as the measure-theoretic or Kolmogorov’s probability, is a foundational approach to probability theory that establishes a rigorous mathematical framework for understanding random events and uncertainty. It was developed by the Russian mathematician Andrey Kolmogorov in the 1930s and has become the standard framework for modern probability theory.
