Question

Use the listing method to write the following set.

Answer 1

Answer:  Third option is correct.

Step-by-step explanation:

Since we have given that

$\{x|x\epsilon N, x < 3\}$

That means the set must have numbers less than 3.

But the set belongs to natural number.

So, it contain only positive integer starting from 1.

So, Set must have

$\{1,2\}$

Hence, Third option is correct.

Answer 2

I believe it is C (1, 2)
