Question

If ∪ = {2, 4, 6, 8, 10, 12, 14, 17}

A = {1, 4, 6, 9, 11, 12}

The set A^C is

• A. {1, 2, 8, 10, 14, 17}
• B. {2, 8, 10, 14, 17}
• C. {2, 8, 10, 14, 17}
• D. Can't be determined

Answer 1

The correct option is D

Can't be determined

Let ∪ be the universal set and A be a subset of ∪. Then the complement of A is the set of all elements of ∪ which are not the elements of A.

∴ A^C = ∪ - A if A ⊂ ∪

Here A ⊄ ∪

So, A^C is not defined here

So, (d) is right option.
