यदि \(A=\{1,2,3,4\}\) है तो (\mathcal{P}(A)) में विषम संख्या वाले एकल उपसमुच्चय कितने हैं?
If \(A=\{1,2,3,4\}\), how many singleton subsets containing odd numbers are in (\mathcal{P}(A))?
Explanation opens after your attempt
Correct Answer
B. (2)
Concept
The odd elements are (1) and (3), so the singleton subsets are ({1},{3}). The number is (2).
Why this answer is correct
The correct answer is B. (2). The odd elements are (1) and (3), so the singleton subsets are ({1},{3}). The number is (2).
Exam Tip
विषम तत्व (1) और (3) हैं इसलिए एकल उपसमुच्चय ({1},{3}) होंगे। संख्या (2) है।
