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.
This lesson teaches how to use Venn diagrams with three sets. The transcript covers examples of finding intersections and unions between the sets, as well as how to read and understand set notation. The lesson emphasizes the importance of distinguishing between intersection sets and union sets, and provides clear explanations and visuals to aid in understanding.
How to use Venn Diagrams with three sets
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.
