यदि \(A=\{1,2,3,4\}\) है, तो (2) को शामिल करने वाले उपसमुच्चयों की संख्या कितनी है?
If \(A=\{1,2,3,4\}\), how many subsets contain (2)?
Explanation opens after your attempt
C. (8)
Concept
Element (2) is fixed, and the remaining (3) elements are optional. Therefore the count is \(2^3=8\).
Why this answer is correct
The correct answer is C. (8). Element (2) is fixed, and the remaining (3) elements are optional. Therefore the count is \(2^3=8\).
Exam Tip
(2) निश्चित है और बाकी (3) सदस्य वैकल्पिक हैं। इसलिए संख्या \(2^3=8\) है।
