यदि \(U={x:x\in \mathbb{Z}, -2\leq x\leq 2}\) है, तो (U) में कितने अवयव हैं?

If \(U={x:x\in \mathbb{Z}, -2\leq x\leq 2}\), how many elements are in (U)?

Explanation opens after your attempt
Correct Answer

C. (5)

Step 1

Concept

Integers from (-2) to (2) are (-2,-1,0,1,2).

Step 2

Why this answer is correct

There are (5) elements in total.

Step 3

Exam Tip

In inclusive inequalities, both boundary values are included. चरण 1: (-2) से (2) तक पूर्णांक (-2,-1,0,1,2) हैं। चरण 2: कुल (5) अवयव मिलते हैं। चरण 3: बंद असमानता में दोनों किनारे शामिल होते हैं।
