In how many ways can gold, silver and bronze medals be awarded among (14) runners?
Explanation opens after your attempt
B. (2184)
Concept
The three medals are different ordered positions, so \(^{14}P_3=14\cdot13\cdot12=2184\). In exams, always count order for medals.
Why this answer is correct
The correct answer is B. (2184). The three medals are different ordered positions, so \(^{14}P_3=14\cdot13\cdot12=2184\). In exams, always count order for medals.
Exam Tip
तीन पदक अलग-अलग क्रमित स्थान हैं, इसलिए \(^{14}P_3=14\cdot13\cdot12=2184\)। परीक्षा में medals में क्रम जरूर गिनें।
