यदि \(A=\{0,{1},2\}\) है, तो निम्न में से कौन सा (\mathcal{P}(A)) का तत्व नहीं है?
If \(A=\{0,{1},2\}\), which of the following is not an element of (\mathcal{P}(A))?
Explanation opens after your attempt
Correct Answer
D. ({0,1})
Concept
(1) itself is not an element of (A); ({1}) is an element. So ({0,1}) is not a subset of (A).
Why this answer is correct
The correct answer is D. ({0,1}). (1) itself is not an element of (A); ({1}) is an element. So ({0,1}) is not a subset of (A).
Exam Tip
(1) स्वयं (A) का तत्व नहीं है बल्कि ({1}) तत्व है। इसलिए ({0,1}), (A) का उपसमुच्चय नहीं है।
