Welcome to the second lesson of the course, and congratulations for completing the first one! In this lesson, we will learn the regions in a Venn diagram. We will learn a more advanced version of Venn diagrams, step by step. First, let's look at this video!
Our Own World: The Universal Set
Usually, when drawing a Venn diagram, we cover the whole Venn diagram with another set, which is Set, in and out of itself. All the sets within this Universal Set are all subsets of the Universal Set. A Universal Set is the set that contains everything we are talking about in a particular situation. We denote the Universal Set using the epsilon \(\varepsilon\).
Now, let's learn more in depth about the intersection and union of sets.

We all know that there are some people who bring lunch, and some who forget, but we all end up eating others' food so that we can try each others' food. So here, whether we bring our own food or not, we end up eating others food, hence, the intersection.
