Answer:
A ∩ B = {6}
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}
