( A U B )' =
A ∩ B
( A ∩ B )'
A' ∩ B'
A' U B'
B - A =
{X/X B and XA}
{X/X B ; XA}
{X/XA;XB}
{X/X A or XB}
n(AUB) = 8; n(A∩B) = 2; n(A) = 3; So n(B) =

Identify element in the intersection of two sets is:
Φ
μ
0
μ'
If A={1,2,3} and B={2,3}, then A Δ B =
{1}
{2,3}
If A = { 2,( 4,5 ),4 }, then which of the following is false?
(4,5)A
{4,5} A
{(4,5)}A
{2,4}A
Given AUB = B. Which of the following is true?
A = B
μ' =
μ - A
μ' - μ
Two set A and B are disjoint sets if and only if:
AUB =Φ
A ∩ B = B
A - B = Φ
A - B = A
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}
