    Do the two sets have any elements in common? You can draw a number line and see if there is any overlap. |dw:1381159993000:dw| Looking at these two number lines, do you see any overlap?

    Well since they have nothing in common and you were suppose to be looking for what the sets had in common because of the little intersection symbol, then the answer would be set that doesn't include any elements also called the empty set since the set is empty.
