Find A ∩ B if A = {3, 6, 9, 12} and B = {2, 4, 6, 8, 10}.

A n B = {6}

Step-by-step explanation:

what's common in sub set A and B

A ∩ B = {6}

Step-by-step explanation:

The symbol ∩ indicates that we are looking for the intersection of the sets A and B. This will be the elements of one set that are also in the other set (common elements in A and B).

the sets are:

A = {3, 6, 9, 12}

B = {2, 4, 6, 8, 10}

elements that are in both sets: 6

In this case only one number is contained in both sets, which is six.

Thus, the intersection is

A ∩ B = {6}
