Answer 1

Answer:

cardinal number equal 5

answer is 5

Answer 2

The cardinal number of the set A = { - 2 , - 1 , 0 , 1 , 2 } is 5

Given :

The set A = { - 2 , - 1 , 0 , 1 , 2 }

To find :

The cardinal number of the set A = { - 2 , - 1 , 0 , 1 , 2 }

Concept :

Cardinality of a set :

The cardinality of a set is defined as the total number of elements in the set.

Solution :

Step 1 of 2 :

Write down the given set

Here the given set is A = { - 2 , - 1 , 0 , 1 , 2 }

Step 2 of 2 :

Find cardinal number of the set

For the set A = { - 2 , - 1 , 0 , 1 , 2 } the distinct elements are - 2 , - 1 , 0 , 1 , 2

So the number of distinct elements in the set A is 5

Now cardinal number of a set is the total number of distinct elements in the set.

Hence cardinal number of the set A = { - 2 , - 1 , 0 , 1 , 2 } is 5
