यदि \(A\cup A'=U\) और \(A\cap A'=\varnothing\), तो (A') को कौन सा समुच्चय बनाता है?
If \(A\cup A'=U\) and \(A\cap A'=\varnothing\), what kind of set is (A') with respect to (A)?
Explanation opens after your attempt
Correct Answer
C. (A) का पूरक समुच्चयComplement of (A)
Concept
Both conditions show that (A) and (A') together form (U) and are disjoint. This is the main identity of complement.
Why this answer is correct
The correct answer is C. (A) का पूरक समुच्चय / Complement of (A). Both conditions show that (A) and (A') together form (U) and are disjoint. This is the main identity of complement.
Exam Tip
दोनों शर्तें बताती हैं कि (A) और (A') मिलकर (U) बनाते हैं और अलग-अलग हैं। यही पूरक की मुख्य पहचान है।
