carrie is finding the set of even numbers within the set of prime numbers. of the sets described which is the universal set

Option 3) Prime numbers is correct

Universal set = The set of Prime numbers.

Step-by-step explanation:

To find the Universal set:

The set of all even numbers are numbers divisible only by 2.

The set of all prime numbers are divisible by 1 and the number itself

Since, we have to take only positive numbers

Carrie has found out the set of even numbers within the set of prime numbers

So, 2 is the only number belongs to this set because 2 is a even prime number.

Hence, universal set should be prime numbers.

Therefore, Option 3) prime numbers is correct.

Universal set = The set of Prime numbers.
