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
(AUB)-(A∩B)=
A
B
A Δ B
μ
In a class 16 students read Mathematics, 17 read science and 6 students read both subjects. So the number of students who read either Mathematics or science =
27
39
33
6
μ = { 1,2,3,4,5 }; A = { 2,4 } then A' =
{1,2,3}
{1,3,5}
{2,4}
{1,2,3,4,5}
A U A' =
Φ
A ∩ A'
A'
A - ( BUC )=
( A - B ) U C
( A - B ) ∩ C
( A - B ) U ( A - C )
( A - B ) ∩ ( A - C )
If , then A - B =
B - A
B - A =
{X/X B and XA}
{X/X B ; XA}
{X/XA;XB}
{X/X A or XB}
If A={1,2,3} and B={2,3}, then A Δ B =
{1}
{2,3}
Which of the following venn diagrams represent (A - B)?
