B

Step-by-step explanation:

{2,4,6} is your answer

Answer 2

The correct answer is option b) {2, 4, 6}.

Given:

The set X = {x | x is an even number, 1 < x < 8}.

To Find:

The set roster form of X.

Solution:

Set can be written in two ways, either we can give a description of the elements of the set or we can directly write down the elements. The former method of writing a set is called the set-builder form of a set and the latter is called as roster form.

Hence, our given set  X = {x | x is an even number, 1 < x < 8} is in set-builder form. To write it in roster form, we need to find every element of the set.

Let us find the elements of set X.

Set X consists of even numbers between (and excluding) 1 and 8, that are

2, 4, and 6.

∴ X = {2, 4, 6}

Hence, the correct answer is option b) {2, 4, 6}.
