$\bigstar{\underline{\underline{{\sf\ \red{ Solution-}}}}}$

From the chapter of sets, we know that:

A∩B is the intersection of the two sets A and B.

In the above figure, 2 sets A and B are given and the shaded region is the area common in both the sets and it is also called as A∩B.

Number of elements given in the set A is as follows:

A = {1, 3, 5, 7, 9}

Number of elements given in the set B is as follows:

B = {2, 3, 5, 7, 11, 13}

As you can see from both the sets that 3, 5, 7 are the common elements among both the sets.

So, A∩B is equal to 3, 5 and 7.

Hence, A∩B = {3, 5, 7}.
