यदि \(A=\{p,q,r\}\), तो (\mathcal{P}(A)) के कितने अरिक्त उचित उपसमुच्चय हैं?
If \(A=\{p,q,r\}\), how many non-empty proper subsets are there in (\mathcal{P}(A))?
Explanation opens after your attempt
C. (6)
Concept
There are \(2^3=8\) total subsets. Removing \(\emptyset\) and (A) leaves (6) non-empty proper subsets.
Why this answer is correct
The correct answer is C. (6). There are \(2^3=8\) total subsets. Removing \(\emptyset\) and (A) leaves (6) non-empty proper subsets.
Exam Tip
कुल उपसमुच्चय \(2^3=8\) हैं। \(\emptyset\) और (A) हटाने पर (6) अरिक्त उचित उपसमुच्चय बचते हैं।
