can anyone intuitively explain me what does a borel field and a borel set mean?Why do we need a Borel field to define all our definitions in probability?

I would like actually like to know that too, so I hope someone else will explain that.
A Borel field is a collection of sets that satisfies certain properties and is commonly used in measure theory. It is named after French mathematician Émile Borel.
A Borel field must contain the empty set and the entire space it is defined on. It must also be closed under countable unions and complements.
A Borel set is a subset of a Borel field, meaning it also satisfies the properties of a Borel field. It is a fundamental concept in mathematical analysis and probability theory.
Borel fields and sets are used to define measures, which are important tools in probability theory and mathematical analysis. They also have applications in other areas of mathematics, such as topology and functional analysis.
Yes, a Borel field can have uncountably infinite sets as long as they satisfy the properties of a Borel field. These sets are known as Borel sets of uncountable rank.
