The correct number of prime numbers from 1 to 50 is 15. The prime numbers within this range are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, and 47.
To clarify, a prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In simpler terms, a prime number has exactly two distinct positive divisors: 1 and itself. For instance, the number 5 is prime because its only divisors are 1 and 5. Other numbers in this range, like 4 or 6, can be divided evenly by numbers other than 1 and themselves (for example, 4 can be divided by 1, 2, and 4).
Therefore, if you count all the prime numbers listed, you will find there are exactly 15 primes from 1 to 50.
