Which of the following sets has 4 elements?

• A = { x/x is an odd number }

• B = { x/x is a vowel }

• C = {x/x is an even number between 1 to 9}

• D = {x/x is an even number from 2 to 10}

What is wrong with the set listed below?

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

• It is not written with roster notation.

• A capital letter is used to represent this set.

• The objects in this set are not unique.

• None of the above.

Which of the following statements is true about the set listed below?

C = {x/x is a prime number less than 20}

• 9 is not an element of C

• 2 is an element of C

• Set C is an infinite set.

• All of the above.

The union of set A and set B,  $A\cup B$ , is the set consists of 

• all the elements in set A and set B.

• the common elements in set A and set B.

• all the elements in set A but not in set B.

• all the elements in set B but not in set A.

The Venn diagram for  $A\cup B$  is represented in green as

• 
• 
• 
• 

The elements in P∪Q are

• {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

• {0, 1, 2, 3, 8, 9, 10}

• {4, 5, 6, 7}

• { }

Base on the Venn diagram given,  $P\subset Q$  . Hence,  $P\cup Q$  can be represents by

• P

• Q

•  $\phi$  

• None of the above

Base on the Venn diagram, which of the following represents  $B\cup C$  

• {1, 9}

• {1, 4, 9, 16)

• {1, 2, 6, 8, 9, 10, 12, 14, 18}

• {1, 2, 4, 6, 8, 9, 10, 12, 14, 16, 18}
