MyOpenMath Assessment: Venn Diagrams, Set Cardinality, and Surveys

This document presents solutions to a MyOpenMath homework assignment focusing on set theory and Venn diagrams. The assignment includes multiple-choice questions on set cardinality, utilizing Venn diagrams to determine the number of elements in various sets. The assessment also features a survey analysis problem, requiring the interpretation of survey data to determine the number of people using different media platforms such as Netflix, Redbox and video stores. The solutions provide detailed answers and explanations for each question, covering topics such as the cardinality of sets, set operations, and the application of Venn diagrams in analyzing survey results. The assignment also contains instructions for creating physical manipulatives for teaching math concepts, including cutting out material cards to create coins and A-Blocks for hands-on learning. These resources are designed to aid students in understanding fundamental mathematical concepts through practical exercises and problem-solving.

A survey was given asking whether they watch movies at home from Netflix, Redbox, or a vid
Use the results to determine how many people use Redbox. Hint: Draw a Venn Diagram
60 only use Netflix 58 only use Redbox
19 only use a video store 9 use only a video store and Redbox
37 use only Netflix and Redbox 29 use only a video store and Netflix
7 use all three 34 use none of these
111 people used Redbox.
