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
Correct Answer

B. (16)

Step 1

Concept

Since (|U-A|=9-5=4), (|\mathcal{P}(U-A)|=24=16). In exams, first find the number of elements in the complement.

Step 2

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.

Step 3

Exam Tip

क्योंकि (|U-A|=9-5=4), इसलिए (|\mathcal{P}(U-A)|=24=16)। परीक्षा में पहले पूरक की संख्या निकालें।
