\(यदि (A={x:x\) एक प्राकृतिक संख्या है और \(2\leq x\leq 6}) है, तो (A) में कितने अवयव हैं\)?
\(If (A={x:x\) is a natural number and \(2\leq x\leq 6}), how many elements are in (A)\)?
Explanation opens after your attempt
B. (5)
Concept
In \(2\leq x\leq 6\), both (2) and (6) are included.
Why this answer is correct
The elements are (2,3,4,5,6), so there are (5) elements.
Exam Tip
While counting, do not forget to include both endpoints. चरण 1: \(2\leq x\leq 6\) में (2) और (6) दोनों शामिल हैं। चरण 2: अवयव (2,3,4,5,6) हैं, जिनकी संख्या (5) है। चरण 3: गिनते समय दोनों सीमाओं को शामिल करना न भूलें।
