यदि \(A=\{4,4,5,6,6,7\}\) को समुच्चय माना जाए, तो (n(\mathcal{P}(A))) कितना होगा?
If \(A=\{4,4,5,6,6,7\}\) is considered as a set, what is (n(\mathcal{P}(A)))?
Explanation opens after your attempt
Correct Answer
B. (16)
Concept
Repeated elements are counted once in a set, so \(A=\{4,5,6,7\}\). Hence (n(\mathcal{P}(A))=24=16).
Why this answer is correct
The correct answer is B. (16). Repeated elements are counted once in a set, so \(A=\{4,5,6,7\}\). Hence (n(\mathcal{P}(A))=24=16).
Exam Tip
समुच्चय में दोहराए गए तत्व एक बार गिने जाते हैं इसलिए \(A=\{4,5,6,7\}\)। इसलिए (n(\mathcal{P}(A))=24=16)।
