\(यदि (U={1,2,3,4,5,6,7,8,9}) और (A={x:x \in U,\ x\) अभाज्य है\(}), तो (A^{c}) क्या है\)?
\(If (U={1,2,3,4,5,6,7,8,9}) and (A={x:x \in U, x\) is prime\(}), what is (A^{c})\)?
Explanation opens after your attempt
Correct Answer
B. ({1,4,6,8,9})
Concept
\(A=\{2,3,5,7\}\), so \(A^{c}={1,4,6,8,9}\). Remember that (1) is not prime.
Why this answer is correct
The correct answer is B. ({1,4,6,8,9}). \(A=\{2,3,5,7\}\), so \(A^{c}={1,4,6,8,9}\). Remember that (1) is not prime.
Exam Tip
\(A=\{2,3,5,7\}\), इसलिए \(A^{c}={1,4,6,8,9}\)। याद रखें कि (1) अभाज्य नहीं है।
