If A = { x: x is a prime number ?17}. Then A in Roster form is
A = {3, 5, 7, 11, 13, 17}
A = {1, 2, 3, 5, 7, 11, 13, 17}
A = {2, 3, 5, 7, 11, 13,17}
None of these
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
A set which contains no element is called __________

Empty set
Equal set
Equivalent set
If A = {a, b, c, d, e} c = {a, e} then A∩C = ___________
{a, b, c, d, e}
{b, c, d}
∅
{a, e}
The set of all subsets of a set A is the _________ of the set A.
Super set
Proper set
Power set
If A = {p, q, r, s, t} B = {p, q, t} then A - B =
{p, q, r, s, t}
{p, q, t}
{r, s}
Given the sets A = {1, 2, 3}, B = {3, 4} C = {4, 5, 6} then A ∪ (B ∩ C) is
{3}
{1, 2, 3, 4}
{1, 2, 4, 5}
{1, 2, 3, 4, 5, 6}
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}, {}}
Let A = {3, 6, 9, 4} B = {a, b, c, f} then A and B are
Equal sets
Equivalent sets
Infinite sets
If a set A containing n elements, then the number of subset of A is
n2
2n
