यदि \(A=\{a,b,c\}\) और \(B=\{c,d,e\}\), तो \(A\cup B\) क्या है?
If \(A=\{a,b,c\}\) and \(B=\{c,d,e\}\), what is \(A\cup B\)?
Explanation opens after your attempt
Correct Answer
C. ({a,b,c,d,e})
Concept
Union contains all distinct elements of both sets, so \(A\cup B={a,b,c,d,e}\). Write repeated elements only once.
Why this answer is correct
The correct answer is C. ({a,b,c,d,e}). Union contains all distinct elements of both sets, so \(A\cup B={a,b,c,d,e}\). Write repeated elements only once.
Exam Tip
संघ में दोनों समुच्चयों के सभी अलग-अलग अवयव आते हैं, इसलिए \(A\cup B={a,b,c,d,e}\)। दोहराए अवयव एक बार लिखें।
