common.
How many students in set R are not in S?
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 total students are in R and S? (Think carefully about this!)
13

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.

A member of a set is called an _____________ of the set
element

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}

{1, 2, 3, 4, ..., 100}.
In the example above, the three dots are called ____________ , and they represent the ________ ______ _________.
 ellipsis
 numbers not listed

There are two common ways of expressing sets. One method is called the ______
method, and the other the ________ method.

The ________ method uses a sentence or phrase that describes the elements of the set.
rule

The ________ method actually lists the elements, or enough to show the set by using ellipsis.
roster

Writing the set {1, 2, 3, 4} as a rule, we would see
{whole numbers between zero and five}.

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}
