\(यदि (A={x:x\in \mathbb{N},x \le 10,x\) is prime\(}) और (B={x:x\in \mathbb{N},x \le 10,x\) is odd\(}) हैं, तो (A\setminus B) क्या है\)?
\(If (A={x:x\in \mathbb{N},x \le 10,x\) is prime\(}) and (B={x:x\in \mathbb{N},x \le 10,x\) is odd\(}), what is (A\setminus B)\)?
Explanation opens after your attempt
Correct Answer
A. ( {2} )
Concept
\(A=\{2,3,5,7\}\) and \(B=\{1,3,5,7,9\}\), so \(A\setminus B={2}\). Remember that (1) is not prime.
Why this answer is correct
The correct answer is A. ( {2} ). \(A=\{2,3,5,7\}\) and \(B=\{1,3,5,7,9\}\), so \(A\setminus B={2}\). Remember that (1) is not prime.
Exam Tip
\(A=\{2,3,5,7\}\) और \(B=\{1,3,5,7,9\}\), इसलिए \(A\setminus B={2}\)। (1) अभाज्य नहीं है।
