Sets

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.

If A = {1,2,3}, B = {3,4,5}, C = {5,6,7}, find A U B U C.

• {1,2,3,4,5,6,7}

• {1,2,3,4,5,6,7,8}

• {1,2,3,3,4,5,5,6,7}

• {3,4,5}
