Question

(x:0<x<5) in roster form​

Answer 1

Given that:

(x:0<x<5)

To find:

Roster form for above mentioned set

Solution:

Let us define set first,

A set is a branch of logical mathematics which deals with the study of collection or group of things or objects.

Here, the objects are the elements or numbers in a set . Let's name a group of elements 1,2,3,4 as A , so the set for this is set A={1,2,3,4}

The set has can be represented in two main forms, they are:

1. Roster form/tabular form

In roster form , the elements or objects of the sets are individually written with a comma seperation in between two curly brackets, i.e. {}.

For example,

a set named B has 12 colours:

set B = {red, blue, purple, green, black, white, yellow, brown,orange, crimson,grey,pink}

2. Set- builder form

In set-builder form, the set consists of elements or objects which have same or common factors between each of them.

For example:

a set X has all the numbers belonging to natural number group less than 100.

it will be denoted as: {x:x is a natural number less than 100}

OR

{x:x is a natural number < 100}

So the final answer for the above set (x:0<x<5) in roster form will be {1,2,3,4}.
