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. M ∩ R

Verified step by step guidance

Identify the sets M and R from the problem: M = {0, 2, 4, 6, 8} and R = {0, 1, 2, 3, 4}.

Recall that the intersection of two sets, denoted by $M \cap R$, is the set of all elements that are common to both M and R.

Compare each element of set M with the elements of set R to find which elements appear in both sets.

List all elements that are found in both M and R to form the intersection set $M \cap R$.

To identify if M and R are disjoint, check if their intersection $M \cap R$ is the empty set $\emptyset$. If it is empty, the sets are disjoint; otherwise, they are not.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Set Intersection

The intersection of two sets includes all elements that are common to both sets. It is denoted by the symbol ∩. For example, if A = {1, 2, 3} and B = {2, 3, 4}, then A ∩ B = {2, 3}. Understanding intersection helps identify shared elements between sets.

Disjoint Sets

Disjoint sets are two or more sets that have no elements in common, meaning their intersection is the empty set (∅). For example, if A = {1, 2} and B = {3, 4}, then A ∩ B = ∅, so A and B are disjoint. Recognizing disjoint sets is important for understanding relationships between sets.

Set Notation and Elements

Set notation uses curly braces {} to list elements, and elements are distinct objects within a set. Understanding how to read and interpret sets, such as U, M, N, Q, and R, is essential for performing operations like intersection and identifying relationships like disjointness.
