A - ( BUC )=
( A - B ) U C
( A - B ) ∩ C
( A - B ) U ( A - C )
( A - B ) ∩ ( A - C )
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 =

Φ
A ∩ A'
A'
Which of the following venn diagrams represent (A - B)?
B - A =
{X/X B and XA}
{X/X B ; XA}
{X/XA;XB}
{X/X A or XB}
μ = { 1,2,3,4,5 }; A = { 2,4 } then A' =
{1,2,3}
{1,3,5}
{2,4}
{1,2,3,4,5}
If A∩B = Φ ; then A,B are called:
Equivalent sets
Disjoint sets
Equal sets
Subsets
A = {x / xN ; x, odd natural number};
B = {x / x N ; x, even natural number}. Then A ∩ B =
N
Q
μ' =
μ - A
μ' - μ
