Which of the following is not a subset of {1,2,3,4}.
{1,2}
{2,3,4}
{1,3,4}
{2,4,5}
If , then A ∩ B =.
A
B
B - A
Φ
n( A U B ) = 51; n( A ) = 20; n( B ) = 44. So n( A ∩ B ) =
31
7
13
115
(AUB)-(A∩B)=
A Δ B
μ
μ' =
μ - A
μ' - μ
( A U B )' =
A ∩ B
( A ∩ B )'
A' ∩ B'
A' U B'
Given AUB = B. Which of the following is true?
A = B
Which of the following venn diagrams represent (A - B)?
A - ( BUC )=
( A - B ) U C
( A - B ) ∩ C
( A - B ) U ( A - C )
( A - B ) ∩ ( A - C )
If A = { 2,( 4,5 ),4 }, then which of the following is false?
(4,5)A
