Sets Intro #1

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

• Superset

• Disjointed Set

• Empty (or Null) Set

• Subset

How many subsets will this set have? A= {a, b, c} ?

• 8

• 6

• 3

• 0

If every element in set A is also in set B, then...

• A is a subset of B
• B is a subset of A
• A = B
• A and B are disjoint

Every set has _____ as one of its subsets (select all that apply.)

• ∅

• 0

• itself

• the real numbers

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.

Determine if these two sets are equal or equivalent.

A = {2, 6, 10, 14}

B = {6, 2, 14, 16}

• Equal

• Equivalent

Set  Q  contains the letters in the word  SISTER .
 Which of the following is set  Q ?

• Q = { S, T, R }
• Q = { I, E }
• Q = { S, I, S, T, E, R }
• Q = { S, I, T, E, R }
