यदि \(A=\{a,b,c,d\}\), \(B=\{b,d,e\}\) और \(C=\{d,e,f\}\) हैं, तो (\(A\setminus B\)\cup\(B\cap C\)) क्या है?
If \(A=\{a,b,c,d\}\), \(B=\{b,d,e\}\) and \(C=\{d,e,f\}\), what is (\(A\setminus B\)\cup\(B\cap C\))?
Explanation opens after your attempt
Correct Answer
A. ({a,c,d,e})
Concept
\(A\setminus B={a,c}\) and \(B\cap C={d,e}\), so the union is ({a,c,d,e}). Find each part separately first.
Why this answer is correct
The correct answer is A. ({a,c,d,e}). \(A\setminus B={a,c}\) and \(B\cap C={d,e}\), so the union is ({a,c,d,e}). Find each part separately first.
Exam Tip
\(A\setminus B={a,c}\) और \(B\cap C={d,e}\), इसलिए संघ ({a,c,d,e}) है। अलग-अलग भाग पहले निकालें।
