"Yes" if the amount in the pool is divisible by one or more prime numbers. Use the Sieve of Eratosthenes, a script, your memory from math class, or the Web for reference. #meta #math

This is an (intentionally or unintentionally) confusing market. It asks whether the final pool size will be a divisible by one or more prime numbers which is true for every integer greater than one (including primes as they are divisible by themselves) by fundamental theorem of arithmetic https://en.wikipedia.org/wiki/Fundamental_theorem_of_arithmetic . But in the description it asks to "Use the Sieve of Eratosthenes" which is an algorithm to generate primes. It can hence be interpreted as "whether the final pool size will be divisible by one or more primes other than itself" that can be translated (without any change in meaning) to "whether the final pool size will be a composite number" . I'm not sure
Uh, I think you may mean "Will the final pool be prime?". Otherwise, I've got some bad news for you: https://en.wikipedia.org/wiki/Fundamental_theorem_of_arithmetic
