यदि \(A={x:x\) अंग्रेजी शब्द sets के अलग-अलग अक्षर हैं(}), तो (n(\mathcal{P}(A))) कितना है?
If \(A={x:x\) is a distinct letter of the English word sets(}), what is (n(\mathcal{P}(A)))?
Explanation opens after your attempt
A. (8)
Concept
The word sets has distinct letters (s,e,t), so (A) has (3) elements. The power set has \(2^3=8\) elements.
Why this answer is correct
The correct answer is A. (8). The word sets has distinct letters (s,e,t), so (A) has (3) elements. The power set has \(2^3=8\) elements.
Exam Tip
शब्द sets में अलग-अलग अक्षर (s,e,t) हैं, इसलिए (A) में (3) तत्व हैं। घात समुच्चय में \(2^3=8\) तत्व होंगे।
