Question

if ∈ = {1,2,3,4,5,6,7,8,9} A = {1,2,3,4,6} B = {4,2,7} find (i) (A ∩ B)'

Answer 1

Answer:

Here's your answer

Step-by-step explanation:

A ∩ B means the elements which are in both the sets overlap zone.

So, ┌(A ∩ B) = the elements which are not in the A B overlap zone.

So, you need to select all of the elements which are not in the overlap zone, which are

{1,3,5,6,7,8,9}
