यदि \(A=\{1,2,3,4\}\) है तो (A) के कितने उपसमुच्चय (1) को नहीं रखते?
If \(A=\{1,2,3,4\}\) then how many subsets of (A) do not contain (1)?
Explanation opens after your attempt
B. (8)
Concept
After removing (1), the remaining (3) elements form \(2^3=8\) subsets. In exams remove the forbidden element first.
Why this answer is correct
The correct answer is B. (8). After removing (1), the remaining (3) elements form \(2^3=8\) subsets. In exams remove the forbidden element first.
Exam Tip
(1) को हटाने पर बचे (3) तत्वों से \(2^3=8\) उपसमुच्चय बनते हैं। परीक्षा में निषिद्ध तत्व को पहले हटाएं।
