यदि \(A=\{a,b,c\}\) और \(B=\{c,d,e\}\) है, तो (\(A\cup B\)-B) क्या है?
If \(A=\{a,b,c\}\) and \(B=\{c,d,e\}\), what is (\(A\cup B\)-B)?
Explanation opens after your attempt
A. ( {a,b} )
Concept
The union is ({a,b,c,d,e}), and removing (B) leaves ({a,b}). This gives the same result as (A-B).
Why this answer is correct
The correct answer is A. ( {a,b} ). The union is ({a,b,c,d,e}), and removing (B) leaves ({a,b}). This gives the same result as (A-B).
Exam Tip
संघ ({a,b,c,d,e}) है और (B) हटाने पर ({a,b}) बचता है। यह (A-B) जैसा परिणाम देता है।
