Given AUB = B. Which of the following is true?
A = B
( A U B )' =
A ∩ B
( A ∩ B )'
A' ∩ B'
A' U B'
If , then A ∩ B =.
A
B
B - A
Φ
A = {x / xN ; x, odd natural number};
B = {x / x N ; x, even natural number}. Then A ∩ B =
μ
N
Q
If , then A - B =
Identify element in the intersection of two sets is:
0
μ'
If A={1,2,3} and B={2,3}, then A Δ B =
{1}
{2,3}
(AUB)-(A∩B)=
A Δ B
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) =
13
3
7
9
