Question

*P = {x I x ∈ N, x ≤ 3 } How to write this set in roster form?* 1️⃣ {0,1,2} 2️⃣ {0,1,2,3} 3️⃣ {1,2} 4️⃣ {1,2,3}. ​

Answer 1

Answer :-

set-builder form:

• $\pmb{P =\{x | x ∈ N, x ≤ 3 \} }$

set-roster form:

• $\mathcal{p=\{1,2,3\} }$

Hence:-

• option 4 is correct

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

P = {x I x ∈ N, x ≤ 3 } How to write this set in roster form

1. {0,1,2}

2. {0,1,2,3}

3. {1,2}

4. {1,2,3}

EVALUATION

Here the given set is

P = {x I x ∈ N, x ≤ 3 }

N denotes the set of natural numbers

Now the natural numbers less than or equal to 3 are 1 , 2 , 3

Hence the required set in roster form is {1,2,3}

FINAL ANSWER

Hence the correct option is 4. {1,2,3}
