Given : A = {2,3,5,7), B = {1,2,3,4,6,12).
To Find :
(a) A - B and B - A
(b) Write the power set of AnB
Solution:
A = {2,3,5,7), B = {1,2,3,4,6,12).
A - B means Elements of A which are not in B
=> A - B = { 5 , 7 }
B - A means Elements of B which are not in A
=> A - B = { 1 , 4 , 6 , 12 }
AnB common elements of A and B
=> AnB = { 2 , 3 }
power set of AnB = 2² = 4
= { {} , {2} , {3} , { 2, 3} }
