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, }
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.
