answer;
A∪B = {1, 2, 3, 5, 7, 8, 9, 11, 13}
A∩B = {5,11}
A∩C = { 8}
B∩C={ } = Ф
Given A = { x: x= 3n-1, n∈N, n<5 }
A= { 2, 5, 8, 11}
[ n= 1⇒ x= 3(1)-1= 2, n=2⇒x= 3(2)-1=5 like that we will calculate up to n=4]
B = { x:x is an odd natural number and x< 15}
B ={ 1, 3, 5, 7, 9, 11, 13 }
C = { x: x=4n, n∈ N, n< 7}
C= { 4, 8, 12, 16, 20, 24 }
A' ={C,O,N ,I}
