यदि \(C={x:x\in\mathbb{Z},-3\leq x\leq 3}\), तो (n(C)) का मान क्या है?
If \(C={x:x\in\mathbb{Z},-3\leq x\leq 3}\), what is the value of (n(C))?
Explanation opens after your attempt
A. (7)
Concept
The integers are (-3,-2,-1,0,1,2,3).
Why this answer is correct
There are (7) elements, so (n(C)=7).
Exam Tip
With \(\leq\), the boundary values are also included. चरण 1: दिए गए पूर्णांक (-3,-2,-1,0,1,2,3) हैं। चरण 2: कुल (7) तत्व मिलते हैं, इसलिए (n(C)=7)। चरण 3: \(\leq\) होने पर सीमा वाले मान भी शामिल किए जाते हैं।
