This document presents a lesson on solving word problems involving sets. It begins by stating the objectives of the lesson which are to apply set operations to word problems, solve word problems using Venn diagrams, and participate in group activities.
•describe the set notation given by the shaded region in the Venn Diagram; and •solve problems using Venn Diagram.
This document provides a lesson on using Venn diagrams to solve word problems involving sets. It presents a word problem about 30 students who play various sports and provides the information in sets and intersections.
1 PROBLEMS INVOLVING SETS. 2 Choose the correct set notation formula for each Venn diagram. B (A ∪ B)’ A ∩ B A’ ∩ B A ∪ B A’ (A ∩ B)’. 3 Shade the region in the Venn diagram that is described by the set notation formula. A ∩ B’ B’ U A B (A ∩ B)’.
Venn diagrams can be used to solve word problems involving union and intersection of sets. Here are some worked out examples: 1. A group of 25 high school students were asked whether they use either Facebook or Twitter or both. Fifteen of these students use Facebook and twelve use Twitter. a. How many use Facebook only?
Here is a suggested jingle for the steps in solving word problems involving sets using Venn Diagrams: Draw a circle, draw another . List the sets, one and then other. Place the info, in each section . Count them up, find intersection . Answer the questions, with no fuss. That's how it's done, with Venn Diagrams! Copyright: © All Rights Reserved.
Set Theory: Venn Diagrams for Problem Solving. In addition to just being fun, we can also use Venn diagrams to solve problems. When doing so, the key is to work from the “inside out,” meaning we start by putting information in the regions of the diagram that represent the intersections of sets.
This document provides examples for solving problems involving sets using Venn diagrams. It begins with an activity that has students identify elements of different sets and represents the sets using a Venn diagram.
The document discusses Venn diagrams and how to solve problems involving sets using Venn diagrams. It provides examples of word problems involving sets and their solutions through drawing and analyzing Venn diagrams.
This document discusses solving problems involving sets using Venn diagrams. It provides examples of word problems involving sets and their solutions. Some examples include problems about students' favorite subjects, places people like to stay, sports students like, and dances guests participated in at a party.
