यदि \(U=\{a,b,c,d,e,f,g,h\}\) और \(A=\{a,b,c\}\) है, तो (\mathcal{P}(U)) के कितने members (A) को subset के रूप में रखते हैं?

If \(U=\{a,b,c,d,e,f,g,h\}\) and \(A=\{a,b,c\}\), how many members of (\mathcal{P}(U)) contain (A) as a subset?

Correct Answer

C. (32)

Step 1

Concept

(A) is fixed and the (5) elements of (U-A) are optional. Therefore the number is \(2^5=32\).

Step 2

Why this answer is correct

The correct answer is C. (32). (A) is fixed and the (5) elements of (U-A) are optional. Therefore the number is \(2^5=32\).

Step 3

Exam Tip

(A) fixed है और (U-A) के (5) तत्व optional हैं। इसलिए संख्या \(2^5=32\) है।
