what is the ratio or prime numbers to composite numbers in this list/10,11,2,13,14,15,16,1,7,18,19,20,21
It is impossible to list the infinite number of prime numbers and composite numbers.
That's an infinite list.
Look for a table of prime numbers. All the odd numbers that are NOT on this list are composite numbers.
That's an infinite list.
Composite numbers are positive integers greater than 1 that have factors other than 1 and themselves. To find all the composite numbers between 1000 and 3000, we can start by listing the prime numbers in that range: 1009, 1013, 1019, 1021, 1031, 1033, and so on. Then, we can identify the numbers that are not prime, which are composite. This process would yield a list of composite numbers between 1000 and 3000.

18 prime numbers
The composite numbers in that list are 22 and 36 - you know they are composite, because they are even numbers. The other numbers are odd and prime.
