Answer 2

A = {4, 6, 8, 9, 10}

Step-by-step explanation:

Natural number : 1, 2, 3, 4,.........

Prime numbers : Those natural numbers which have only two factors ( 1 or itself )

eg : 2, 3, 5, 7,...

Composite number : All natural numbers which are not prime except 1 are called composite numbers.

eg : 4, 6, 8, ....

Now, in roster form of a set we write the elements of set under the flower bracket i.e. {} and separated them by commas.

Here, set A = {x:x∈ N, x is a composite number and  x < 11 }

So, elements of A = 4, 6, 8, 9, 10

Thus, required roster form,

A= {4, 6, 8, 9, 10}
