Question

If A={ 2,5,7,8,9} and b={7,8,10,11} find A ∆ B​

Answer 1

Step-by-step explanation:

f A={ 2,5,7,8,9} and b={7,8,10,11} find A ∆ B

Answer 2

Answer:

A∩B = { 7 , 8 }

Step-by-step explanation:

Given that A = { 2 , 5 , 7 , 8 , 9 }

          and B = { 7 , 8, 10 , 11 }

To find A∩B .

∩ = intersection.

Intersection ∩ is the elements of the two or more sets in which the elements are lies same in two or more sets.

So, A∩B =   { 2 , 5 , 7 , 8 , 9 } ∩  { 7 , 8, 10 , 11 }

     A∩B = { 7 , 8 }.

Therefore , the intersection of the sets A and B is { 7 , 8 }.
