यदि \(U=\{1,2,3,4,5,6,7,8,9,10\}\) और \(A=\{2,3,5,7\}\) है, तो (|\mathcal{P}(A')|) कितना होगा?
If \(U=\{1,2,3,4,5,6,7,8,9,10\}\) and \(A=\{2,3,5,7\}\), what is (|\mathcal{P}(A')|)?
Explanation opens after your attempt
Correct Answer
C. (64)
Concept
Here (A') has (6) elements, so (|\mathcal{P}(A')|=26=64). In exams, always find complement with respect to (U).
Why this answer is correct
The correct answer is C. (64). Here (A') has (6) elements, so (|\mathcal{P}(A')|=26=64). In exams, always find complement with respect to (U).
Exam Tip
यहां (A') में (6) तत्व हैं, इसलिए (|\mathcal{P}(A')|=26=64)। परीक्षा में complement हमेशा (U) के सापेक्ष निकालें।
