Let A = {1, 2, 3} and B = {2, 4}. What is A ∪ B? Choices: (A){1, 3, 4} (B){1, 2, 3, 4} (C){4} (D){2}

Define Union of Sets: The union of two sets A and B, denoted by A ∪ B, is the set of elements that are in A, or in B, or in both. To find A ∪ B, we combine all the unique elements from both sets without repeating any elements.Identify Sets A and B: Set A = {1, 2, 3} and Set B = {2, 4}. To find the union, we list all the elements from both sets: {1, 2, 3, 4}. We do not repeat the element '2' because it is present in both sets.Combine Unique Elements: The union of sets A and B, A ∪ B, is therefore {1, 2, 3, 4}.

\newline

Choices:

\newline

(A)

\{1, 3, 4\}

\newline

(B)

\newline

(C)

\{4\}

\newline

(D)

\{2\}

Define Union of Sets: The union of two sets $A$ and $B$ , denoted by $A \cup B$ , is the set of elements that are in $A$ , or in $B$ , or in both. To find $A \cup B$ , we combine all the unique elements from both sets without repeating any elements.
Identify Sets A and B: Set A = $\{1, 2, 3\}$ and Set B = $\{2, 4\}$ . To find the union, we list all the elements from both sets: $\{1, 2, 3, 4\}$ . We do not repeat the element ' $2$ ' because it is present in both sets.
Combine Unique Elements: The union of sets $A$ and $B$ , $A \cup B$ , is therefore $\{1, 2, 3, 4\}$ .
