A Venn diagram is shown below: What are the elements of (a ∩ b)’?

Solution:

(A ∩ B) means a set that contains the common elements of sets A and B. From the Venn diagram shown it is apparent that the common elements are 1 and 2.

A = {1, 2, 3, 4} and 

B = {1, 2, 5, 6}

A ∩ B = {1, 2}

Therefore we can write ,

A ∩ B = {1, 2}

A Venn diagram is shown below: What are the elements of (a ∩ b)’?

Summary:

The elements of (A ∩ B) are set denoted by the A ∩ B = {1, 2}.
