Question

Let U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

A = {1, 2, 3, 4}

Then, $A^c$ is

• A. {1, 2, 3, 4}
• B. {5, 6, 7, 8, 9, 10}
• C. {2, 3, 4, 5,}
• D. None of these

Answer 1

The correct option is B

{5, 6, 7, 8, 9, 10}

U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

A = {1, 2, 3, 4}

$A^c=U-A$ = {5, 6, 7, 8, 9, 10}
