यदि \(U=\{a,b,c,d,e\}\) और \(B=\{a,e\}\) है, तो \(B^{c}\) में कितने अवयव हैं?
If \(U=\{a,b,c,d,e\}\) and \(B=\{a,e\}\), how many elements are in \(B^{c}\)?
Explanation opens after your attempt
Correct Answer
B. (3)
Concept
\(B^{c}={b,c,d}\), so the number of elements is (3). While counting, look only inside (U).
Why this answer is correct
The correct answer is B. (3). \(B^{c}={b,c,d}\), so the number of elements is (3). While counting, look only inside (U).
Exam Tip
\(B^{c}={b,c,d}\), इसलिए अवयवों की संख्या (3) है। गिनती करते समय केवल (U) के अंदर देखें।
