यदि (|U|=9), (|A|=5) और \(A \subseteq U\) है, तो (|\mathcal{P}(U-A)|) का मान क्या है?
If (|U|=9), (|A|=5), and \(A \subseteq U\), what is the value of (|\mathcal{P}(U-A)|)?
Explanation opens after your attempt
B. (16)
Concept
Since (|U-A|=9-5=4), (|\mathcal{P}(U-A)|=24=16). In exams, first find the number of elements in the complement.
Why this answer is correct
The correct answer is B. (16). Since (|U-A|=9-5=4), (|\mathcal{P}(U-A)|=24=16). In exams, first find the number of elements in the complement.
Exam Tip
क्योंकि (|U-A|=9-5=4), इसलिए (|\mathcal{P}(U-A)|=24=16)। परीक्षा में पहले पूरक की संख्या निकालें।
