Part of video series Sets
Taught by mrbrianmclogan
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
A union B union C should be {1, 2, 3, 4, 5, 8} because 8 is also in B.
A intersect B union C should be {1, 2, 3, 4, 5} because 5 is also in C.
How to use Venn Diagrams with three sets
  • How do you find intersection and union of sets with a Venn Diagram?
  • What is a Venn Diagram?
  • What is the intersection and union of sets?
  • If A = {2}, B = {2, 5, 8}, C = {1, 2, 3, 4, 5}, and U = {1, 2, 3, 4, 5, 7, 8, 14}, what are B intersect C, A intersect C, A intersect B intersect C, A union B union C, A union B intersect C, and A intersect B union C?
This lesson shows how to reason out intersections and unions of 3 sets using a Venn Diagram. The concepts of union and intersection are explained and several example problems are shown, but please take note of the corrections in a couple of the problem solutions.
