Hint: In the given question, we need to write the prime numbers from 1 to 20 and we need to write them using the listing method in the set. Now, we know that prime numbers are all those numbers which are divisible by the number itself or by 1.

Complete step-by-step solution:
According to the question, we know that we need to write some elements in the set using the listing method. Now, we know that the listing method is a method to list all the elements in the set, separating each element by the comma and enclosing the whole set with the curly braces.
Now, in this question we know that a set is a collection of elements and prime numbers are all those numbers which are divisible by itself or 1.
Therefore, prime numbers between 1 and 20 are 2, 3, 5, 7, 11, 13, 17, 19.
Hence, the set of prime numbers between 1 and 20 is {2, 3, 5, 7, 11, 13, 17, 19}.

Note: In such questions, we need to take care of the concept of prime and composite numbers and even and odd numbers. After this, we need to make the set of such numbers, that is we need to make sure of the definition and the various forms in which we can enter the elements in the set.
