Correct Answer
B. किसी बच्चे को zero coin मिल सकता हैA child may get zero coins
Concept
When zero is allowed, place (n) stars and (r-1) bars. In exams treat \({}^{n+r-1}C_n\) and \({}^{n+r-1}C_{r-1}\) as the same.
Why this answer is correct
The correct answer is B. किसी बच्चे को zero coin मिल सकता है / A child may get zero coins. When zero is allowed, place (n) stars and (r-1) bars. In exams treat \({}^{n+r-1}C_n\) and \({}^{n+r-1}C_{r-1}\) as the same.
Exam Tip
Zero allowed हो तो (n) stars और (r-1) bars रखे जाते हैं। परीक्षा में \({}^{n+r-1}C_n\) और \({}^{n+r-1}C_{r-1}\) same मानें।
