I'm not sure But i think its Empty set

anonymous · Answer

Why do you think empty set?

anonymous · Answer

i honestly dont know but i actually change my mind from empty set to 1,2 because the fact that i see if you put the numbers together they give you the numbers in order from 1 to 10...i dont know if that makes sense to you?

anonymous · Answer

Do you know what the $\cap$ does?

anonymous · Answer

It means "both". It takes everything that is in both sets.
On the other hand $\cup$ means "either".

anonymous · Answer

so what does that mean? so its actually 1,2?

anonymous · Answer

The $\cap$ doesn't take $1$ because it isn't in both sets.

anonymous · Answer

If nothing is in both, then it is just an empty set.

Okay Thanks
