And welcome to the second project of Math Things. Today we answer the question: What percent of odd numbers are prime? Well, around 2,000, 30% of odd numbers are prime. But around 100,000 19.172% of odd numbers are prime. And you'll notice that the percentage decreases slower but even further for higher values of n. This, of course, begs the question, is it ever 0%? No. There is always one prime that can be found between n and 2n, even when n is very very large. But because it rounds to the nearest whole number, it appears to be 0. This literally would mean that no primes are found above some high number n.
Thanks to @PullJosh for the rounding technique.
