यदि \(U=\{1,2,3,4,5,6,7,8\}\) और \(A=\{2,4,6,8\}\) है, तो (\mathcal{P}(U)) के कितने members (A') से disjoint हैं?
If \(U=\{1,2,3,4,5,6,7,8\}\) and \(A=\{2,4,6,8\}\), how many members of (\mathcal{P}(U)) are disjoint from (A')?
Explanation opens after your attempt
B. (16)
Simple Explanation
(A') से disjoint subsets केवल (A) के subsets होंगे, इसलिए संख्या \(2^4=16\) है। परीक्षा में disjoint from complement का अर्थ subset of original set समझें। / Subsets disjoint from (A') are exactly subsets of (A), so the number is \(2^4=16\). In exams, understand disjoint from complement as subset of the original set.
