Question

Please help and explain

Answer 1

C

Explanation:

I tend to remember the "U" symbol as meaning "or", whilst the "n" symbol means aNd.

using this method we can see that the question is asking us to find which diagram fills in a shade that is NOT x OR y.

• Option A shades Y
• Option B shades X aNd Y (X n Y)
• Option D shades X

So therefore the answer must be C as it shades in all area that isn't X OR Y!
