यदि \(A=\{1,2,3\}\), तो \(\mathcal{P}(A)\setminus{\emptyset,A}\) में कितने तत्व होंगे?

If \(A=\{1,2,3\}\), how many elements are in \(\mathcal{P}(A)\setminus{\emptyset,A}\)?

Explanation opens after your attempt
Correct Answer

C. (6)

Step 1

Concept

(\mathcal{P}(A)) has \(2^3=8\) elements. Removing \(\emptyset\) and (A) leaves (6) elements.

Step 2

Why this answer is correct

The correct answer is C. (6). (\mathcal{P}(A)) has \(2^3=8\) elements. Removing \(\emptyset\) and (A) leaves (6) elements.

Step 3

Exam Tip

(\mathcal{P}(A)) में \(2^3=8\) तत्व हैं। \(\emptyset\) और (A) हटाने पर (6) तत्व बचते हैं।
