Placing a question mark at the end of an expression does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered.
The set of numbers which 3 does not belong is the set of even numbers.
Any well-defined set of numbers.
The set of even numbers is the set of all the numbers that are divisible by 2 (or multiples of 2).
No. The set of irrational numbers has the same cardinality as the set of real numbers, and so is uncountable.The set of rational numbers is countably infinite.
It is the set of Real numbers.
Many infinite sets appear in mathematics: the set of counting numbers; the set of integers; the set of rational numbers; the set of irrational numbers; the set of real numbers; the set of complex numbers. Also, certain subsets of these, such as the set of square numbers, the set of prime numbers, and others.
No, it is not.
real numbers
In a certain sense, the set of complex numbers is "larger" than the set of real numbers, since the set of real numbers is a proper subset of it.
the set of real numbers
All of the natural numbers.
The set of integers, the set of rational numbers, the set of real numbers, the set of complex numbers, ...
The set of numbers which 3 does not belong is the set of even numbers.
This set of numbers is called "Whole Numbers".
The set of real numbers.
If you mean larger by "the set of whole numbers strictly contains the set of natural numbers", then yes, but if you mean "the set of whole numbers has a larger cardinality (size) than the set of natural numbers", then no, they have the same size.
Whole numbers are the set of natural or counting numbers inclding zero
