If A = [1, 2}, B = {1, 2, 3, 4} then
B is a subset of A
A is a subset of B
C and B are equal sets
None of these
Let A = { 1, 3, 5, 7, 9} and B = { 3, 4, 5, 6} and U = { 1, 3, 5, 7, 9}. find ( A-B)

For any two sets A and B, ( A-B) U ( B- A) =
(A - B) U A
(B - A) UB
(AUB) - (A∩B)
(AUB) ∩ (A∩B)
The number of non - empty subsets of the set {1,2,3,4} is

If A = {a, c, e, g} B = {b, d, e, f} then A - B =
{b, d, f}
{g}
{f}
{a, c, g}
Given A and B are sets and A - B = A, then
A and B are disjoint sets
A and B are over lapping sets
A is the subset of B
If A∩B = B then
A ⊂ B
B ⊂ A
A = ∅
B = ∅
If A and B are any two sets, then A∩ (A∪B) is equal to
A
