Find A ∩ B if A = {3, 6, 9, 12} and B = {2, 4, 6, 8, 10, 12}
The intersection of two sets is a set containing all the elements the two set have in common. Only include elements you see in both set A and set B.
2,3,4,5,6,7,8,9,10,11,12
No, that's the union of the sets. The question is the intersection.
