Answer 2

Answer:

The number of elements in the set {A,B,C} are:

                            3

Step-by-step explanation:

Set--

A set is a well defined collection of distinct objects.

By well defined we mean that there is no ambiguity or confusion regarding the inclusion or  exclusion of any element in the set.

The elements of the set are also known as the objects.

The set with 4 elements is denoted by : {a,b,c,d}

where a,b,c and d are distinct objects.

Here we have a set as:

               {A,B,C}

            Hence, there are 3 elements in the set.
