Textbook Question
Let U = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}, M = {0, 2, 4, 6, 8}, N = {1, 3, 5, 7, 9, 11, 13}, Q = {0, 2, 4, 6, 8, 10, 12}, and R = {0, 1, 2, 3, 4}.Use these sets to find each of the following. Identify any disjoint sets. N ∪ R
Verified step by step guidance1
Identify the sets given: \( N = \{1, 3, 5, 7, 9, 11, 13\} \) and \( R = \{0, 1, 2, 3, 4\} \).
Recall that the union of two sets \( A \cup B \) is the set containing all elements that are in \( A \), in \( B \), or in both.
To find \( N \cup R \), list all unique elements from both sets \( N \) and \( R \) without repeating any element.
Write down the combined set with all elements from \( N \) and \( R \).
To identify if \( N \) and \( R \) are disjoint, check if they have any elements in common. If there are no common elements, the sets are disjoint; otherwise, they are not.

1mKey Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Set Union
The union of two sets combines all elements from both sets without duplication. For sets A and B, A ∪ B includes every element that is in A, or in B, or in both. This operation helps in finding all unique elements across the given sets.

Disjoint Sets
Disjoint sets are sets that have no elements in common. If the intersection of two sets is empty, they are disjoint. Identifying disjoint sets helps understand relationships between sets and whether they share any common elements.

Set Notation and Elements
Understanding set notation and how elements are listed is essential. Sets are collections of distinct objects, and elements are the individual members. Recognizing elements and their membership in sets allows accurate operations like union and intersection.
