## Intersection and Union of Sets Worksheets

#### High School Statistics - HSS.CP.A.1

What Is the Difference Between an Intersection and a Union of Sets? A set is a collection of numbers that is written within curly brackets, set brackets, or braces, with a comma between each member of the set. The members in a set do not necessarily specify a characteristic. Sets are a fundamental concept in mathematics, and without applying them in different situations, sets have no real meaning. There are a variety of properties and functions that we can apply on sets and these include intersection, union, and compliments. Unions and intersections are two opposite functions. A union operation, when applied on sets, results in a set that contains elements that are at least in one of the sets in question. We denote the operation of union using "U" and use "or" to represent the operation in words. An intersection operation when applied on sets, results in a set that contains the elements that are present in all sets in question. We denote the operation of intersection using "∩" and use "and" to represent the operation in words. With the help of these worksheets and lessons students learn how to detect and interpret unions and intersections between statistical probability sets.

### Printable Worksheets And Lessons  #### Given Open Sets Practice Sheets

In this series you are given numbered sets and are asked to create Venn Diagrams.

• Practice 3 - Intersection (and): The set of elements in common. Do not repeat an element.
• Practice 4 - Union (or): The set of elements from all sets. Do not repeat an element.

#### Homework Sheets

The homework sheets test your complete mastery of the topic. Read each question very carefully.

• Homework 1 - C notation: C means NOT. Example: P(G)C means P(NOT G).
• Homework 2 - The Universal Set, represents the suit of hearts in a 52-deck of cards excluding the Ace, {2,3,4,5,6,7,8,9,10,J,Q,K).
• Homework 3 - Create the Venn Diagram and answer the questions given the following events.

#### Quizzes on Sets

The quizzes expect you to understand set notation in addition to the basic concepts.

• Quiz 1 - The Universal Set includes all the letters from A – P, {A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P}.
• Quiz 2 - Model this scenario: In Kiki's class 10 students have Smart phones, 12 Flip phones, and 2 No phone.
