Question

give example in sigma algebra​

Answer 1

Answer:

Example: If we roll a die, Ω = {1; 2; 3; 4; 5; 6}. In the probability space, the σ-algebra we use is σ(Ω), the σ-algebra generated by Ω. Thus, take the elements of Ω and generate the "extended set" consisting of all unions, compliments, compliments of unions, unions of compliments, etc.
