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 }

List the elements of A

• {2,3}

• {2,3,5,9}

• {1,2,3,4,5}

• {5,9}

If A= {10,20,30,40},B={20,40,60} and C = {10,20,40,60,80}, find A Ո B Ո C

• {20,40}

• {20,40,60}

• {10,20,30,40,50,60,80}

• {10,20,30,...}

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}

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}

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.

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

• Superset

• Disjointed Set

• Empty (or Null) Set

• Subset
