Set Theory/Math Logic

Question

Is there any way to prove that

 

- Every point in A intersect B is greater than or

equal to 1?

 

- The intersection of two sets has a point in common
with another set?

 

If there is no way to prove it, how do you explain why and what is wrong with these two statements?

Answer 1

- Every point in A intersect B is greater than or
equal to 1?

Nothing said about the elements in A and B.

Points are not equal to a number.

 

- The intersection of two sets has a point in common
with another set?

Entirely dependent on the elements in each of the sets
