  4. In a Venn diagram, what shape represents the universal set?
    A rectangle
  5. In a Venn diagram, subsets of the universal set are represented by what shape?
    a circle

  6. Answer the question below given the following information. Set R has a total of
    10, set S has a total of 7, and set T shows that S and R have 4 objects in
    common.

    How many students in set R are not in S?
    6

  7. Answer the question below given the following information. Set R has a total of
    10, set S has a total of 7, and set T shows that S and R have 4 objects in
    common.

    How many total students are in R and S? (Think carefully about this!)
    13

  8. Answer the question below given the following information. Set R has a total of
    10, set S has a total of 7, and set T shows that S and R have 4 objects in
    common.

    Why are there not 17 total students in R + S?
    Because you don't want to add the same students twice.
  9. A member of a set is called an _____________ of the set
    element
  10. How would you write an abbreviated set containing the counting numbers from one to fifty, inclusive? (Choose one option below)
    {1, 2, 3, 5, ...}
    {1, 3, 5, 9, ... 50}
    {1, 2, 3, 4, 5, ... 50}
    {1, 7, 11, 13, 33, ... 50}
    {1, 2, 3, 4, 5, ... 50}
  11. {1, 2, 3, 4, ..., 100}.
    In the example above, the three dots are called ____________ , and they represent the ________ ______ _________.
    • ellipsis
    • numbers not listed
  12. There are two common ways of expressing sets. One method is called the ______
    method, and the other the ________ method.
    • rule
    • roster
  13. The ________ method uses a sentence or phrase that describes the elements of the set.
    rule
  14. The ________ method actually lists the elements, or enough to show the set by using ellipsis.
    roster
  15. Writing the set {1, 2, 3, 4} as a rule, we would see
    {whole numbers between zero and five}.
  16. Writing the set {1, 2, 3, 4} as a rule, we would see, {whole numbers between zero and five}. Note 0 and 5 were not included in the set. If you wanted to include the numbers 0 and 5 in the set, how would you have written the rule?
    {whole numbers between zero and five, inclusive}
