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}

Answer 2

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)
