No, a finite set can be a set of anything - as long as it has a finite number of members.
Some examples of finite sets are:
- the set of black Chess pieces in a chess set (16 members)
- the set of all red 2010 cars made by Ford (unknown but finite number of members)
- the set of planets orbiting our sun (8 members)
- the set of numbers between 14 and 23 that are integer multiples of pi (3 members) {5*pi, 6*pi, 7*pi} The elements of this set are all Irrational Numbers
- the set of marbles inside a pint jar (unknown but finite number of members)
- the set of Bowling balls in a 2 liter soda bottle (0 members as a bowling ball is too big to fit in a 2 liter soda bottle)
- etc.

The set of all counting numbers less than one million is it finite or infinite?
Finite.
Is the set of whole numbers closed under subtraction?
It depends on your definition of whole numbers. The classic definition of whole numbers is the set of counting numbers and zero. In this case, the set of whole numbers is not closed under subtraction, because 3-6 = -3, and -3 is not a member of this set. However, if you use whole numbers as the set of all integers, then whole numbers would be closed under subtraction.
The set of contains all the whole numbers and their opposites?
That is called the set of "integers".
What is the cardinality of set b?
If set b is finite then the cardinality is the number of elements in it. If it is not finite then it depends on whether its elements can be put into 1-to-1 correspondence with the natural numbers (cardinality = Aleph Null) or with irrationals (Aleph-One).
Is the set of whole numbers are closed under multiplication?
If you can never, by multiplying two whole numbers, get anything but another whole number back as your answer, then, YES, the set of whole numbers must be closed under multiplication.
Are all whole numbers a finite set?
no
Is the set of all common multiples of two given whole numbers is finite?
Yes, that is true.
What are the finite sets -all whole numbers -all natural numbers less than 100000 -all letters of the alphabet -all odd numbers?
The whole number form an infinite set.The natural numbers less than 100000 form a finite set(either 99999 or 100000 members, depending on whether 0 is considered a natural number).The letter of the alphabet form a finite set (26 members for the English alphabet).The odd numbers form an infinite set.
Is the set of whole numbers greater than 8 is infinite or finite?
Infinite.
Is a set of prime numbers an finite set?
Finite, no.
The set of all counting numbers less than one million is it finite or infinite?
Finite.
What do you call a set of numbers with an exact number of points?
This is called a discrete set (all points isolated) or a finite set. Finite sets are always discrete.
Is the set of natural numbers less than -2 finite or infinite?
The empty set is a finite set.
What is finite sets?
A finite set is a set that has numbers you can count. Its not like infinite with no end it has an end.
What numbers are in the set of natural numbers and which are in the set of whole numbers?
All of the natural numbers.
What are the examples of finite and infinite sets in your daily life?
The set of your friends is finite. The set of counting numbers (part of which you will use to count your friends) is infinite.
How does the set of natural numbers differ from the set of whole numbers?
0 and negative integers are all whole numbers but they are not natural numbers.
