. How many elements are sets of even prime numbers

A. One

B. Two

C. Three

D. Four

Best Answer

Ans. Correct option is A.

Firstly, we have to know the difference between even number and prime number.

Even number

The number which is divided by 2 is called even number. for example,2, 4, 6, 8, 10, 12, 14, 16 etc.

Prime number

Prime numbers are figures which have exactly two factors 1 and themselves.

For illustration the first 5 high figures are 2, 3, 5, 7 and 11. By difference, figures with further than two factors are called composite numbers.

Indeed high number

The only even prime number is 2. All other even numbers can be divided by 2 so other even figures will have three factors as 1, 2 and themselves so there's only one even prime number.
