Module 1: Logic and Set Theory
Lesson 3 Summary
In this lesson you learned about unions and intersections of sets. You represented unions and intersections by using Venn diagrams and the connecting words and, or, and not, as well as proper mathematical notation.
The diagrams on page 31 of your textbook provide a good summary of these terms.
You also used these concepts to solve real-world problems using sets and the principle of inclusion and exclusion. Using the skills you built in this lesson, you have seen that many items with similarities and differences can be described mathematically. The use of sets will show others your thought process behind the inclusion of items within a set and your ability to describe scenarios mathematically.
In Module 2 you will learn about odds and probabilities where the application of set theory can be very helpful and useful. But first, go to Lesson 4, which provides an overview of the course project you will encounter in Mathematics 30-2.
