यदि \(A=\{a,b,c,d\}\) है तो (A) के कम से कम दो अवयवों वाले उपसमुच्चयों की संख्या क्या है?
If \(A=\{a,b,c,d\}\), how many subsets of (A) have at least two elements?
Explanation opens after your attempt
C. (11)
Concept
There are (16) total subsets and (1+4=5) subsets with zero or one element. So the answer is (16-5=11).
Why this answer is correct
The correct answer is C. (11). There are (16) total subsets and (1+4=5) subsets with zero or one element. So the answer is (16-5=11).
Exam Tip
कुल उपसमुच्चय (16) हैं और शून्य या एक अवयव वाले (1+4=5) हैं। इसलिए उत्तर (16-5=11) है।
