यदि \(A=\{a,b,c,d,e\}\) है, तो (\mathcal{P}(A)) में (a) या (b) में से कम से कम एक रखने वाले subsets कितने हैं?

If \(A=\{a,b,c,d,e\}\), how many subsets in (\mathcal{P}(A)) contain at least one of (a) or (b)?

Explanation opens after your attempt
Correct Answer

C. (24)

Step 1

Concept

Total subsets are \(2^5=32\), and subsets containing neither (a,b) are \(2^3=8\). Therefore the answer is (32-8=24).

Step 2

Why this answer is correct

The correct answer is C. (24). Total subsets are \(2^5=32\), and subsets containing neither (a,b) are \(2^3=8\). Therefore the answer is (32-8=24).

Step 3

Exam Tip

कुल subsets \(2^5=32\) हैं और (a,b) दोनों न रखने वाले \(2^3=8\) हैं। इसलिए उत्तर (32-8=24) है।
