यदि (n(A)=5), तो (P(A)) के विषम संख्या वाले अवयवों के उपसमुच्चयों की संख्या क्या है?
If (n(A)=5), what is the number of subsets in (P(A)) having an odd number of elements?
Explanation opens after your attempt
C. (16)
Concept
Odd-sized subsets are \(2^{5-1}=16\). This identity helps in quick counting.
Why this answer is correct
The correct answer is C. (16). Odd-sized subsets are \(2^{5-1}=16\). This identity helps in quick counting.
Exam Tip
विषम आकार के उपसमुच्चय \(2^{5-1}=16\) होते हैं। यह पहचान तेज गिनती में मदद करती है।
