Question

Find the intersection of the three sets: A = {–4, 3, 10}, B = {3, 6, 10, 15}, C = {–4, 10, 20}.
(Points : 1)
       {10}
       {–4, 10}
       {–4, 3, 10}
       {–4, 3, 6, 10, 15, 20}

what does the word intersect mean in this equation

anonymous · Answer

intersect is something they all contain.  so the middle set  {10}  it is the only one in all three sets
(union is all of them together)
