Hind Fadhil Abbas · Journal of Southwest Jiaotong University · 2020
The sigma field is a branch of mathematics that refers to the gathering of subsets includes sample space. It is useful in establishing a formal mathematical probability definition. The sets that occur in the sigma field are responsible for constituting various events in the presence of available sample space. In this paper, we focus on sigma fields. The main aim of this paper is to define the sigma field. Different types of sigma fields, along with the basic mathematics and examples, are also elaborated upon.
