A = {x / xN ; x, odd natural number};
B = {x / x N ; x, even natural number}. Then A ∩ B =
μ
N
Q
Φ
A - ( BUC )=
( A - B ) U C
( A - B ) ∩ C
( A - B ) U ( A - C )
( A - B ) ∩ ( A - C )
n( A U B ) = 51; n( A ) = 20; n( B ) = 44. So n( A ∩ B ) =
31

115
Identify element in the intersection of two sets is:
0
μ'
If A = {1,2,3,4,5,6}; B = {2,4}; C = {2,4,6,8} then A - ( B ∩ C ) =
{5,6}
{1,5,6}
{1,2,5,6}
n(AUB) = 8; n(A∩B) = 2; n(A) = 3; So n(B) =
3
