Answer:
A set is a collection of well-defined and distinct objects. Every object of the collection forming a set is called a member or element of the set. When an object is a member of a set we say that the object belongs to the set.
Any collection of objects is not a set. Let us consider the following collection of objects.
(i) The first four natural numbers
(ii) The collection of the letters of the word TERRACOTTA
(iii) Four consecutive whole numbers
The members of collection (i) are 1, 2, 3 and 4. These objects are well-defined. Now we have to decide whether a particular object belongs to the collection or not. For example, 3 is a member of the collection, while 5 is no. Also, the members of the collection are distinct or different from each other. Thus, the collection is a set.
But collection (ii) is not a set because letter ‘R’, ‘A’ and ‘T’ occurs in it twice, and hence, the objects belonging to the collection are not distinct. If we take only one ‘R’, only one ‘A’ and only one ‘T’ in place of two ‘R’s, ‘A’s and ‘T’s, we get the collection T, E, R, A, C, O which is a set.
Again, collection (iii) is not a set as we are unable to decide whether an object belongs to the collection or not. Here, in this case 3 may belong to the collection or it may not. The same is true for any other whole number.
