What type of set is denoted as either { } or ∅?

• Superset

• Disjointed Set

• Empty (or Null) Set

• Subset

A = {x : x is a letter in the word SEAT}

B = {x : x is a letter in the word TASTE}

Determine if these two sets are equal or equivalent.

• Not equal because seat has 4 letters and taste has 5 letters.

• Equivalent because they have the same letters

• Equal because each set has the same cardinality and the same letters.

It is a collection of well-defined group of objects.

• Element

• Set

• Cardinality

• Universal Set

Set D is the set of the distinct letters in the word mathematics. Write the set using the Roster method.

• D = {m, a, t, h, e, m, a, t, i, c, s}

• D = {m, a, t, h}

• D = {m, a, t, h, e, i, c, s}

• D = {m, a, t, h, i, c, s}

Set C is the set of whole numbers less than 9. Write the set using the Roster method.

• C = {1, 2, 3, 4, 5, 6, 7, 8, 9}

• C = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

• C = {1, 2, 3, 4, 5, 6, 7, 8}

• C = {0, 1, 2, 3, 4, 5, 6, 7, 8}

Which of the following is the symbol for element of?

• ∅

A set whose elements are countable.

• finite

• infinite

• equal

• equivalent

What is the cardinality of a null set?

• 0

• 1

• infinite

• undefined
