Example Question #1 : Subsets
Which of the following is true about the relationship between sets?
The subset symbol should be read as "is a subset of" So it's the first letter is a subset of the second letter. To be a subset, all of its elements must be contained in the other set.
The only one of these relationships that is true (where the entire set on the left is in the right set) is
The elements of B, 4, 5, 6, and 8 all appear in set D.
Example Question #1 : Real Analysis
Which of the following is not a subset of Set A:{ 
{
{
{
{
{
Step 1: A subset of a set must have elements in Set A. If any number in the subset is not in the original set, then that subset is not a subset of that set.
{
Example Question #1 : Subsets
Which of the following is NOT a subset of Set A:
Step 1: Recall the definition of a subset. A subset is a small part of a bigger given set; ALL numbers in the subset must be in the original set.
Step 2: We look at the original set and then look at the answers. If there is any answer that has an element that is not showing up in the original set, than that is the right answer.
Let's look at: 
The other two answers with brackets are subsets of the original set. All elements in the subsets are present in the original set.
The empty set is always a subset of any given set.
The answer is
Example Question #1 : Subsets
What is a subset of 
Step 1: Define a subset. A subset of a bigger set is a smaller part where all the elements in the subset must be present in the bigger set.
The answer is 
Example Question #1 : Subsets
Which of the following is a subset of the set: 
Step 1: Define a subset
A subset of a big set is a set that has some of the elements that are in the bigger parent set.
The answer is 
Example Question #1 : Finite, Infinite, Countable, Not Countable Classifications
Which of the following sets is not an infinite set??
All numbers 
All whole numbers 
All whole numbers
Step 1: Determine the difference between Infinite and Finite Sets...
Finite Sets: A set that has very limited elements in it
Infinite Sets: Any set where I can always find another number between two given boundaries.
The Set of integers and rational numbers are infinite sets..
All numbers between 
The set of whole numbers between 
Example Question #1 : Set Theory
Which of the following is a finite set?
All real numbers between 
All whole numbers between 
All whole numbers between
Note: The set of real numbers 
Step 1: The set of real numbers between two numbers 
Step 2: The set of whole numbers between
