\(यदि (A={x:x\in\mathbb{N},x\) अभाज्य है और \(x<2}), तो (A) क्या है\)?
\(If (A={x:x\in\mathbb{N},x\) is prime and \(x<2}), what is (A)\)?
Explanation opens after your attempt
C. \(\varnothing\)
Concept
The natural number less than (2) is (1).
Why this answer is correct
(1) is not a prime number.
Exam Tip
Since no prime number is found, the set is empty. चरण 1: (2) से छोटी प्राकृतिक संख्या (1) है। चरण 2: (1) अभाज्य संख्या नहीं होती। चरण 3: कोई अभाज्य संख्या न मिलने पर समुच्चय रिक्त है।
