Guided Practice (8.01) - Sets & Subsets

Suppose a universal set consists of multiples of 5 that are no greater than 40. Two subsets are created from the universal set. Set A contains the even numbers and Set B contains the numbers greater than 25. Which is the universal set (U)?

• Superset

• Empty (or Null) Set

• Disjointed Set

• Subset

If U = {11, 12, 13, 14, 15, 16, 17, 18, 19, 20} and A = {12, 13, 14, 20}, what is the complement of A?

• {11, 15, 16, 17, 18, 19}

• {11, 12, 13, 14, 15, 16, 17, 18, 19, 20}

• {12, 13, 14, 20}

• {15, 16, 17, 18, 19}

If A = {1, 3, 5, 7, 9} and B = {2, 3, 5, 7}, what is A ∩ B?

• {2, 3, 5, 7}

• {3, 5, 7}

• {2, 3, 5, 7, 9}

• {1, 2, 3, 5, 7, 9}
