यदि \(A=\{1,2,3,4,5\}\) है तो (\mathcal{P}(A)) में कितने एक तत्व वाले समुच्चय होंगे?
If \(A=\{1,2,3,4,5\}\) then how many one element sets are in (\mathcal{P}(A))?
Explanation opens after your attempt
C. (5)
Concept
Each original element forms one singleton subset. So there will be five one element subsets.
Why this answer is correct
The correct answer is C. (5). Each original element forms one singleton subset. So there will be five one element subsets.
Exam Tip
हर मूल तत्व से एक एकल उपसमुच्चय बनता है। इसलिए पांच एक तत्व वाले उपसमुच्चय होंगे।
