Question

If ∪ = {2, 4, 6, 8, 10, 12, 14, 17}, where ∪ is Universal set.

B = {1, 4, 6, 9, 10, 11, 12}

The set B^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 B is the set of all elements of ∪ which are not the elements of B.

∴ B^C = ∪ - B if B ⊂ ∪

Here B ⊄ ∪

So, B^C is not defined here.
