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
A U A' =
A ∩ A'
A'
A = {x / xN ; x, odd natural number};
B = {x / x N ; x, even natural number}. Then A ∩ B =
N
Q
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}
If A={1,2,3} and B={2,3}, then A Δ B =
{1}
{2,3}
A - ( BUC )=
( A - B ) U C
( A - B ) ∩ C
( A - B ) U ( A - C )
( A - B ) ∩ ( A - C )
(AUB)-(A∩B)=
A
