यदि \(^{n}P_4=360\times{}^{n}C_4\) कहा जाए, तो यह कथन कैसा है?
If it is said that \(^{n}P_4=360\times{}^{n}C_4\), what type of statement is it?
Explanation opens after your attempt
A. गलत, क्योंकि सही गुणक (4!=24) हैFalse, because the correct multiplier is (4!=24)
Concept
\(^{n}P_r=^{n}C_r r!\), so for (r=4) the multiplier is (24). In exams verify the multiplier using factorials.
Why this answer is correct
The correct answer is A. गलत, क्योंकि सही गुणक (4!=24) है / False, because the correct multiplier is (4!=24). \(^{n}P_r=^{n}C_r r!\), so for (r=4) the multiplier is (24). In exams verify the multiplier using factorials.
Exam Tip
\(^{n}P_r=^{n}C_r r!\) है, इसलिए (r=4) पर गुणक (24) होगा। परीक्षा में multiplier को factorial से verify करें।
