यदि \(|A|=5\) है, तो \(\mathcal{P}(A)\) में \(A\) और \(\varnothing\) दोनों को छोड़कर कितने सदस्य बचेंगे?
If \(|A|=5\), then how many members remain in \(\mathcal{P}(A)\) after excluding both \(A\) and \(\varnothing\)?
Explanation opens after your attempt
B. (30)
Concept
Total members are \(2^5=32\). After excluding (A) and \(\varnothing\), (32-2=30) remain.
Why this answer is correct
The correct answer is B. (30). Total members are \(2^5=32\). After excluding (A) and \(\varnothing\), (32-2=30) remain.
Exam Tip
कुल members \(2^5=32\) हैं। (A) और \(\varnothing\) हटाने पर (32-2=30) बचते हैं।
