There are 12 composite (and 8 primes) in the first twenty whole numbers. So the probability of randomly choosing a non-prime is 12/20 or 60%.
what number is not a prime factor
You find the first 20 prime numbers and add them together. There is no formula for generating a sequence of prime numbers and so none for the series of their sums.You find the first 20 prime numbers and add them together.

Well, darling, if you're a prime number less than 10 and adding 10 or 20 gives you another prime number, you must be the number 3. Adding 10 gives you 13 (prime) and adding 20 gives you 23 (also prime). Looks like you're a prime catch!
The first prime number after 30 is 31
The first prime after 20 is 23.
23
A prime number can be less than 20, but it is not a requirement that the number has to be under 20 to be considered prime. Here is a list of all the prime numbers under 20: 2, 3, 5, 7, 11, 13, 17, and 19 .
23^2=529

what number is not a prime factor
The first prime number after 14 is 17.
2 is the first prime number.
5 is the greatest prime factor of 20.
20 is not a prime number because 5 and 4 10 and 2 can also go into 20 not just 20 and 1
11 + 101 = 112
