Answer 1

Hi...☺

Here is your answer...✌

Given Set,

A = { x : -3 < x < 3 , x ∈ Z }

First we write Set in roster form
We have,

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

Number of elements in set A,
n(A) = 5

We know that

If a Set has 'p' elements
Then, number of subsets of Set is ${2}^{p}$

There is 5 elements in set A

Therefore,

Number of subsets of Set A = ${2}^{5}$ = 32

HENCE,

The correct option is (D) 32
