If only (2) members are to be chosen from (7) players which formula is used?
Explanation opens after your attempt
C. \(^{7}C_2\)
Concept
There is no post or order in choosing members so combination is used. In exams do not count order when the phrase only select appears.
Why this answer is correct
The correct answer is C. \(^{7}C_2\). There is no post or order in choosing members so combination is used. In exams do not count order when the phrase only select appears.
Exam Tip
सदस्य चुनने में पद या क्रम नहीं है इसलिए combination लगेगा। परीक्षा में only select शब्द पर order न गिनें।
