If \(U=\{1,2,3,4,5,6\}\) and \(A=\{1,3,5\}\), how many elements are in (A')?
Explanation opens after your attempt
Correct Answer
B. (3)
Concept
(A') contains (2,4,6), so it has three elements. While finding complement look only inside (U).
Why this answer is correct
The correct answer is B. (3). (A') contains (2,4,6), so it has three elements. While finding complement look only inside (U).
Exam Tip
(A') में (2,4,6) होंगे इसलिए तीन तत्व हैं। पूरक निकालते समय केवल (U) के अंदर देखें।
