Set Operations (Diagnostic Test)

The Union of Sets is the set whose elements are contained in either Set A or Set B or both.

• True

• False

If A = { a, e, i } and B = { a, e, i, o, u }, then A ∩ B = { a, e, i }.

• True

• False

The complement of a set is the set of elements in A but not in B.

• True

• False

If A = { 1, 2, 3, 4, 5 } and B = { 1, 3, 5 }, then A ∪ B = A.

• True

• False

The intersection of sets, is the set containing the elements that are in both A and B.

• True

• False

If M = { 2. 3, 5 } and N = { 2, 4, 6, 8 },then M - N = { 2, 3, 5 }.

• True

• False

The difference of two sets is the set of elements in the universal set that are not in A.

• True

• False

Let A = {1, 2, 3, 4, 5} B = {2, 3, 4} C = {2, 4, 6, 8}, Find: A U B

• {1, 2, 3, 4, 5}

• {1, 3, 5}

• { }

• {2, 3, 4}

Let A = {1, 2, 3, 4, 5} C = {2, 4, 6, 8}, Find: A ∩ C

• 1, 2, 3, 4, 5}

• {1, 3, 5}

• {2, 4, 6, 8}

• {2, 4}

Let A = {1, 2, 3, 4, 5} C = {2, 4, 6, 8}, Find: A U C

• {1, 2, 3, 4, 5, 6, 8}

• {1, 2, 3, 4, 5}

• {2, 4, 6, 8}

• {2, 4, 5}
