यदि (A=\(-\infty,2]\) और (B=\(0,\infty\)) हैं, तो (\(A\cap B\)\cup\(A\setminus B\)) किसके बराबर है?
If (A=\(-\infty,2]\) and (B=\(0,\infty\)), then (\(A\cap B\)\cup\(A\setminus B\)) equals which set?
Explanation opens after your attempt
A. (A)
Concept
\(A\cap B\) and \(A\setminus B\) are disjoint parts of (A), and their union is (A). View such identities as partitioning a set.
Why this answer is correct
The correct answer is A. (A). \(A\cap B\) and \(A\setminus B\) are disjoint parts of (A), and their union is (A). View such identities as partitioning a set.
Exam Tip
\(A\cap B\) और \(A\setminus B\), (A) के अलग-अलग भाग हैं और उनका संघ (A) है। ऐसे पहचान प्रश्न में भागों को विभाजन की तरह देखें।
