यदि \(A=\{1,1,2,2,3\}\) को समुच्चय माना जाए, तो (n(\mathcal{P}(A))) कितना होगा?
If \(A=\{1,1,2,2,3\}\) is considered as a set, what is (n(\mathcal{P}(A)))?
Explanation opens after your attempt
Correct Answer
A. (8)
Concept
Repeated elements are counted only once in a set, so \(A=\{1,2,3\}\). Hence (n(\mathcal{P}(A))=23=8).
Why this answer is correct
The correct answer is A. (8). Repeated elements are counted only once in a set, so \(A=\{1,2,3\}\). Hence (n(\mathcal{P}(A))=23=8).
Exam Tip
समुच्चय में दोहराए गए तत्व एक बार ही गिने जाते हैं, इसलिए \(A=\{1,2,3\}\)। इस कारण (n(\mathcal{P}(A))=23=8)।
