To find :

  • we need to find A ∩ B'

Solution :

  • U = {1 ,2 ,3 ,4 ,5 ,6 ,7 ,8 ,9 ,10}
  • A = {1, ,2 ,3 }
  • B = {6 ,7 }

B' = All elements of all sets accept set B elements.

  • B = {6 ,7 }

›› B ' = {1 ,2 ,3 ,4 ,5 ,8 ,9 ,10 }

Now ,

  • A ∩ B'

A = {1 ,2 ,5 }

B' = {1 ,2 ,3 ,4 ,5 ,8 ,9 ,10 }

›› A ∩ B' = { 1 ,2 ,5} = A

Hence,

  • A ∩ B' = A or {1 ,2 ,5 }
