Question

*A = {a I a ∈ W, but a ∉ N} What type of set A is?* 1️⃣ Singleton Set 2️⃣ Empty Set 3️⃣ Infinite Set 4️⃣ None of these ​

Answer 1

Answer:

1️⃣ Single ton set

Step-by-step explanation:

1. A=0
2. because the whole number which do not belongs to natural number's is 0
3. So,it is a single ton set

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

A = { a I a ∈ W , but a ∉ N } What type of set A is

1. Singleton Set

2. Empty Set

3. Infinite Set

4. None of these

EVALUATION

Here the given set is

A = { a I a ∈ W , but a ∉ N }

Now W is the set of whole numbers

W = { 0 , 1 , 2 , 3 , 4 , 5 , ... }

N is the set of natural numbers

N = { 1 , 2 , 3 , 4 , 5 , ... }

Thus 0 is the only element which belongs to W but does not belong to N

Thus we get

A = { a I a ∈ W , but a ∉ N }

= { 0 }

So the set A contains only one element

We know that if a set contains only one element then the set is called singleton set

FINAL ANSWER

Hence the correct option is 1. Singleton Set
