यदि \(A=\{p,q,r,s,t,u\}\) है, तो (\mathcal{P}(A)) में (p) और (q) दोनों को न रखने वाले subsets कितने हैं?
If \(A=\{p,q,r,s,t,u\}\), how many subsets in (\mathcal{P}(A)) contain neither (p) nor (q)?
Explanation opens after your attempt
Correct Answer
B. (16)
Concept
After removing (p) and (q), (4) elements remain, so there are \(2^4=16\) subsets. In exams, remove both elements for a neither condition.
Why this answer is correct
The correct answer is B. (16). After removing (p) and (q), (4) elements remain, so there are \(2^4=16\) subsets. In exams, remove both elements for a neither condition.
Exam Tip
(p) और (q) हटाने पर (4) तत्व बचते हैं, इसलिए \(2^4=16\) subsets होंगे। परीक्षा में neither condition में दोनों तत्व हटाएं।
