Let G = {5, 10, 15} and H = {5, 10, 12, 15}. What is G ∪ H? Choices: (A){10, 15} (B){5, 10, 12, 15} (C){5, 10, 15} (D){12}

Combine unique elements: To find the union of two sets, we combine all the unique elements from both sets without repeating any elements. G = {5, 10, 15} H = {5, 10, 12, 15} G ∪ H = {all unique elements from G and H}Include missing elements: List all the elements from set G and then include any elements from set H that are not already in G. G ∪ H = {5, 10, 15, 12}Arrange in ascending order: Arrange the elements of the union set in ascending order for clarity. G ∪ H = {5, 10, 12, 15}

Q. Let

G = \{5, 10, 15\}

and

H = \{5, 10, 12, 15\}

. What is

G \cup H

\newline

Choices:

\newline

(A)

\{10, 15\}

\newline

(B)

\{5, 10, 12, 15\}

\newline

(C)

\{5, 10, 15\}

\newline

(D)

\{12\}

Combine unique elements: To find the union of two sets, we combine all the unique elements from both sets without repeating any elements. $\newline$ $G = \{5, 10, 15\}$ $\newline$ $H = \{5, 10, 12, 15\}$ $\newline$ $G \cup H = \{\text{all unique elements from } G \text{ and } H\}$
Include missing elements: List all the elements from set $G$ and then include any elements from set $H$ that are not already in $G$ . $G \cup H = \{5, 10, 15, 12\}$
Arrange in ascending order: Arrange the elements of the union set in ascending order for clarity. $\newline$ $G \cup H = \{5, 10, 12, 15\}$
