यदि \(A=\{2,5,8,11\}\) और \(B=\{1,5,9,11\}\) है, तो (\(A\cup B\)-\(A\cap B\)) क्या है?
If \(A=\{2,5,8,11\}\) and \(B=\{1,5,9,11\}\), what is (\(A\cup B\)-\(A\cap B\))?

Concept
Removing the common elements (5) and (11) from the union leaves ({1,2,8,9}). This gives the non-common parts.

Exam Tip
संघ से समान भाग (5) और (11) हटाने पर ({1,2,8,9}) बचता है। यह सामान्य भाग को हटाकर अलग-अलग भाग देता है।
