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
C. (6)
Concept
(\mathcal{P}(A)) has \(2^3=8\) elements. Removing \(\emptyset\) and (A) leaves (6) elements.
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.
Exam Tip
(\mathcal{P}(A)) में \(2^3=8\) तत्व हैं। \(\emptyset\) और (A) हटाने पर (6) तत्व बचते हैं।
