Let U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, A = {1, 2, 5} B = {6, 7} then A ∩ B' is
B'
A
A'
B
The smallest set A such that A {1,2} = {1, 2, 3, 5, 9} is

If A = {a, b, c} then power set of A is
{a, b, c, ∅}
{{a}, {b}, {}}
{{a}, {b}, {c}, {a, b}, {a, c}, {b, c}, {a, b, c}}
{{a}, {b}, {c}, {a, b}, {a, c}, {b, c}, {a, b, c}, {}}
Two equal sets are always
Disjoint set
Singleton set
Two sets are said to be equal, if they contain
Equal sign
Equal number of elements
Same elements
