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
The list of prime numbers is infinite. There are two factors for each.
Prime numbers that are next to each other on the list of prime numbers.
It is impossible to list all the prime numbers as there are an infinite number of them. The list of prime numbers starts: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, ... Suppose you could list all the prime numbers and have done so - there is no prime number which is not on the list. Multiply them all together and add 1. This number is not divisible by any of the listed prime numbers as there is always a remainder of 1. So either this new number is a prime number, or there is another prime number not listed which will divide into it. Which means that the list was not all the prime numbers; meaning it is impossible to list all the prime numbers.

A prime number is divisible only by 1 and itself. Some examples would include: 2,3,5,7,11,13,53, and 97. This is not an exhaustive list.
Look up a list of prime numbers (a Google search for "prime numbers" or "list of prime numbers" should do); every number (greater than 1) that is NOT a prime number is composite.
