Question for 2.11

It asks "Find all Even Prime Numbers" is it asking for the amount? Or to list each of the even prime numbers.

Please include the course name in your question.  I assume this is for Math Challenge I-B Number Theory class.

The way the question is asking, "Find all even primes", indicates that you need to list all of them.

Now think about the prime numbers (without worrying about even or odd).  What are they? Can you list some of them? How many of them are even numbers?
