Answer:
The set {x | x is an even prime number, x<150} has 1 element.
Step-by-step 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 | 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 | x is an even prime number, x<150} has 1 element.
