यदि \(U=\{a,b,c,e\}\) और \(A=\{a,b,c,d\}\) है तो पूरक (A') निकालने से पहले कौन सी समस्या है?
If \(U=\{a,b,c,e\}\) and \(A=\{a,b,c,d\}\), what problem occurs before finding (A')?
Explanation opens after your attempt
Correct Answer
A. \(A\subseteq U\) नहीं है\(A\subseteq U\) is not true
Concept
Complement is normally taken when \(A\subseteq U\). Here (d) is not in (U), so there is a problem.
Why this answer is correct
The correct answer is A. \(A\subseteq U\) नहीं है / \(A\subseteq U\) is not true. Complement is normally taken when \(A\subseteq U\). Here (d) is not in (U), so there is a problem.
Exam Tip
पूरक सामान्यतः तब लिया जाता है जब \(A\subseteq U\) हो। यहां (d), (U) में नहीं है इसलिए समस्या है।
