Let a = {101, 202, 303, 404, 505} and b = {101, 404}. what is a ∩ b?

A ∩ B = {101, 404}

Step-by-step explanation:

The given sets are A = {101, 202, 303, 404, 505} and B = {101, 404}

We have to find A ∩ B.

As we know A ∩ B is the term we use to find common terms in both.

Or intersection of two sets A and B is the set that contains all the elements of A that belongs to B, or inversely all elements of set B that belongs to A.

Now common terms of set A and set B are (101, 404).

Therefore A ∩ B = {101, 404} is the answer..
