Two distinct prime numbers are always coprime but converse is not true.

Yes, you are correct.

### Explanation:
- **Two distinct prime numbers are always coprime**: If you have two distinct prime numbers, say \( p_1 \) and \( p_2 \), then their only common divisor is 1. This is because the only divisors of a prime number are 1 and the number itself. Since \( p_1 \) and \( p_2 \) are distinct, they cannot divide each other, so their greatest common divisor (GCD) is 1. Thus, they are coprime.

- **The converse is not true**: The converse would state that if two numbers are coprime, then they must be prime. However, this is not true. For example, consider the numbers 8 and 15. These numbers are coprime because their GCD is 1, but neither 8 nor 15 is a prime number (8 is divisible by 2 and 15 is divisible by 3 and 5). Therefore, the converse statement is false.

**Tip:** When checking if two numbers are coprime, the quickest method is to find their greatest common divisor (GCD). If the GCD is 1, they are coprime.
