Question

Let U = {1, 2, 3, 4, 5, 6, 7, 8, 9} X = {1, 2, 3, 4, 5} Y = {2, 4, 6} and Z = {2, 4, 5, 6}. Find the following sets: (i)X’ (ii)Y’ (iii)(X∪Y) (iv)(X∪Z)′ (v)(X′)‘ (vi)(Y–Z)

Answer 1

U = {1, 2, 3, 4, 5, 6, 7, 8, 9} X = {1, 2, 3, 4, 5} Y = {2, 4, 6} and Z = {2, 4, 5, 6

If `U ={1, 2, 3, 4, 5, 6, 7, 8, 9 }` , `A= {2, 4, 6, 8}` and`B = { 2, 3, 5, 7
