Answer 2

Answer: A set is a group of numbers or nouns which are being selected at a specific topic.

Step-by-step explanation:

{Dulaj, Darren, Niraj, Samali, Aini, 98, 38, 5, 3, Chair, Table, $\sqrt{465}$}

These are names, Numbers (Integers) Objects and irrational numbers. Above all are the data.

first we will take like this as an example.

{ Names}

This is a set as you can see. It says;

Names={ Dulaj, Darren, Niraj, Samali, Aini}

Now that is a clear defined set, as all the names are able to be counted and is very specific to the data provided.

{Integers}

This is a set as you can see. It says;

Integers= {98, 38, 5, 3,}

Now that is a clear defined set, as all the numbers are able to be counted and is very specific to the data provided.

{Nouns}

This is a set as you can see. It says;

Nouns= {Dulaj, Darren, Niraj, Samali, Aini, Chair, Table}

Here, you can see that when it comes to nouns, we can include the elements both names and the object names. Earlier, it was clearly asked for the set {Names} and that is a well defined set which contains only names. But here, we have both the names and objects.

So this is a not a well defined set.

{Irrational numbers from 0-100}

Now in this, you can see that irrational numbers are a lot. And also from 0-100, its uncountable.
