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
Correct Answer

A. (,8,)

Step 1

Concept

(A-B={1,3,5}) has (3) elements. Therefore (n(\mathcal{P}(A-B))=23=8).

Step 2

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).

Step 3

Exam Tip

(A-B={1,3,5}) में (3) तत्व हैं। इसलिए (n(\mathcal{P}(A-B))=23=8)।
