38. Venn Diagram of complement of A
Universal set is the largest set.
Let A be a subset of U.
Then Aβ is the complement of A, which
is the set of all elements which are Not
in A.
41. DISJOINT SETS
Two sets A and B are called disjoint when they have
nothing in common. The sets which are Not disjoint are called
Overlapping sets. Example:
46. Example:02
U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
T is the set of all multiples of 2
F is the set of all multiples of 4
Write T and F in Tabular form.
Find Tβ and Fβ.
Draw the Venn Diagram.
