Question

$\text{For two sets}A=\{5,6,7,8\}\&B=\{7,8,9,11\}.A\cup B=$

• A. {5, 6, 7, 8, 9, 10, 11}
• B. {5, 6, 7, 8, 9, 11}
• C. {9, 11}
• D. {5, 6, 7, 8}

Answer 1

The correct option is B

{5, 6, 7, 8, 9, 11}

$A\cup B$ contains the elements that belong to set $A$ (or) set $B$ (or) both.

$A\cup B=\{5,6,7,8,9,11\}$
