यदि \(A=\{1,2,3,4,5,6\}\), \(B=\{2,4,6\}\), तो (n(\mathcal{P}(A-B))) कितना है?
If \(A=\{1,2,3,4,5,6\}\), \(B=\{2,4,6\}\), what is (n(\mathcal{P}(A-B)))?
Explanation opens after your attempt
A. (,8,)
Concept
(A-B={1,3,5}) has (3) elements. Therefore (n(\mathcal{P}(A-B))=23=8).
Why this answer is correct
The correct answer is A. (,8,). (A-B={1,3,5}) has (3) elements. Therefore (n(\mathcal{P}(A-B))=23=8).
Exam Tip
(A-B={1,3,5}) में (3) तत्व हैं। इसलिए (n(\mathcal{P}(A-B))=23=8)।
