Let A = {101, 202, 303, 404, 505} and B = {101, 404}. What is A ∩ B?

Solution:

Given A= {101, 202, 303, 404, 505} and B ={101, 404}

The common part between the sets is called intersection

The intersection of sets is denoted by the symbol ‘∩’

Set A has 5 elements and set B has 2 elements

Clearly, we can see that element 101 and 404 is present in both sets

Hence, they are the common elements.

So, A ∩ B = {101, 404}

Let A = {101, 202, 303, 404, 505} and B = {101, 404}. What is A ∩ B?

Summary:

If A = {101, 202, 303, 404, 505} and B = {101, 404} then A ∩ B is {101, 404}.
