यदि \(A\cap B=\varnothing\) और \(A\cup B=U\) है, तो (B) किसके बराबर होगा?

If \(A\cap B=\varnothing\) and \(A\cup B=U\), then (B) is equal to what?

Explanation opens after your attempt
Correct Answer

A. \(A^c\)

Step 1

Concept

If two sets are disjoint and together form (U), then they are complements of each other. Hence \(B=A^c\).

Step 2

Why this answer is correct

The correct answer is A. \(A^c\). If two sets are disjoint and together form (U), then they are complements of each other. Hence \(B=A^c\).

Step 3

Exam Tip

यदि दो समुच्चय असंबद्ध हों और मिलकर (U) बनाएं, तो वे एक-दूसरे के पूरक होते हैं। इसलिए \(B=A^c\) होगा।
