d. How many even prime numbers are there?
There is only one even prime number, which is 2.
Which months have a prime number of days
The prime-numbered months are:
1. January - 31 days
2. March - 31 days
3. May - 31 days
4. July - 31 days
5. August - 31 days
6. October - 31 days
7. December - 31 days
To determine how many even prime numbers there are, we need to understand that prime numbers are only divisible by 1 and themselves. However, even numbers are always divisible by 2, meaning they will never be prime, except for the number 2 itself.
Therefore, there is only one even prime number, which is 2. No other even numbers can be prime.
To determine the number of even prime numbers, we need to recall the definition of prime numbers, which are natural numbers greater than 1 that have no positive divisors other than 1 and themselves. However, even numbers are divisible by 2, so the only even prime number is 2. No other even numbers can be prime because they are divisible by 2.
Therefore, there is only one even prime number, which is 2.
