यदि \(A=\{1,2,3,4,5\}\) और \(B=\{6,7,8\}\) है, तो (A-B) क्या होगा?
If \(A=\{1,2,3,4,5\}\) and \(B=\{6,7,8\}\), what is (A-B)?
Explanation opens after your attempt
B. ( {1,2,3,4,5} )
Concept
The two sets are disjoint, so no element is removed from (A). For disjoint sets, (A-B=A).
Why this answer is correct
The correct answer is B. ( {1,2,3,4,5} ). The two sets are disjoint, so no element is removed from (A). For disjoint sets, (A-B=A).
Exam Tip
दोनों समुच्चय असंयुक्त हैं, इसलिए (A) से कोई अवयव नहीं हटेगा। असंयुक्त समुच्चयों के लिए (A-B=A) होता है।
