Question

How many elements are in the set​ x is an even prime​ number, x<150​?

Answer 1

The set x is an even prime number, x<150 has 1 element.

Explanation:

Prime Numbers: The numbers which have no factors other than 1 and the number itself are called prime numbers.

Even Numbers are those numbers which are completely divisible by 2.

So, the only EVEN PRIME NUMBER = 2

Now, Set = x is an even prime number, x<150

So, the set has {2} as its only element.

Hence, the total elements in the set is 1.

Or, the set x is an even prime number, x<150 has 1 element.
