• Universal Set
• Empty (or Null) Set
• Disjointed Set
• Complement of a Set

What does this symbol ( ∩ ) represent in set theory?

• Union
• Intersection
• Disjointed
• Subset

{1,2,3,4,5,6} which set is a subset of this?

• {1,3,5}

• {0,1,2}

• {4,6,8}

• {1.1,2,3}

If A = {{1,2}, 3, 5, {6}}, then {6} ∈ A.

• TRUE

• FALSE

It is a collection of well-defined objects.

Which of following are the possible subsets of

U = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}?

• A = {2, 4, 6, 8}

• B = {1, 3, 5, 7}

• C = {5, 6, 7, 10}

• D = {-2, 3, 4, 5}

Which is NOT an element of the set of countries in Southeast Asia?
