यदि \(A=\varnothing\) और सार्वत्रिक समुच्चय (U) है, तो \(A^{c}\) क्या होगा?
If \(A=\varnothing\) and the universal set is (U), what is \(A^{c}\)?
Explanation opens after your attempt
Correct Answer
B. (U)
Concept
\(\varnothing\) has no element, so its complement is the whole (U). In exams, write the complement of the empty set as (U).
Why this answer is correct
The correct answer is B. (U). \(\varnothing\) has no element, so its complement is the whole (U). In exams, write the complement of the empty set as (U).
Exam Tip
\(\varnothing\) में कोई अवयव नहीं होता, इसलिए उसका पूरक पूरा (U) है। परीक्षा में रिक्त समुच्चय का पूरक तुरंत (U) लिखें।
