By definition, an even number is evenly divisble by 2, and a prime number is evenly divisble only by 1, and by itself. The number 2 is therefore the only even number that is also a prime number.
Is 2.9 a prime number?
No, 2.9 is not a prime number. Prime numbers are integers greater than 1 that have no positive divisors other than 1 and themselves. Since 2.9 is not an integer but a decimal number, it does not fit the definition of a prime number.
