यदि \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{1,3,5,7,9\}\) और \(B=\{2,3,5,8\}\) है, तो (|\mathcal{P}((A-B)')|) कितना है?
If \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{1,3,5,7,9\}\), and \(B=\{2,3,5,8\}\), what is (|\mathcal{P}((A-B)')|)?
Explanation opens after your attempt
Correct Answer
C. (64)
Concept
(A-B={1,7,9}), so its complement has (6) elements. Hence the power set size is \(2^6=64\).
Why this answer is correct
The correct answer is C. (64). (A-B={1,7,9}), so its complement has (6) elements. Hence the power set size is \(2^6=64\).
Exam Tip
(A-B={1,7,9}), इसलिए उसके complement में (6) तत्व हैं। अतः power set size \(2^6=64\) है।
