Oh, dude, let me break it down for you. So, prime numbers are like those special numbers that are only divisible by 1 and themselves, right? So, between 1 and 25, we've got 9 prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, and 23. And since there are like 25 numbers in total, the fraction of prime numbers is 9/25. Math can be fun, right?
YES. There are 9 prime numbers from 1 to 25. There are only 6 prime numbers from 26 to 50.
