Question

Write the roster form for the given set:

“Set of even prime numbers."

Answer 1

Even numbers are the numbers that are completely divisible by$2$. Examples: $2,4,6,8$etc.

Prime numbers are the numbers having two factors only, i.e, one and the number itself. They are not divisible by any other number apart from 1 and the number itself.

Examples of Prime number: $2,3,5,7$etc

If we consider the prime numbers we can find that $2$ is the only even prime number.

Hence roster form will be represented as $\left\{2\right\}$
