GIVING A MEDAL TO ANSWER

Find the intersection of the sets A = {1, 4, 8, 9} and B = {2, 4, 7, 9, 11}.

A null set
B {4, 9}
C {1, 2, 7, 8, 11}
D {1, 2, 4, 7, 8, 9, 11}

Answer 1

The intersection is the set of elements, that are common to both sets. Since 4 and 9 are in both A and B, the intersection would be {4, 9}
