In how many ways can a group of (4) players be formed from (8) players?(8) खिलाड़ियों में से (4) खिलाड़ियों का समूह कितने तरीकों से बनाया जा सकता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (70)(70)
A group has no order, so (\binom{8}{4}=70). In exams, the word group usually indicates combination.समूह में क्रम नहीं होता इसलिए (\binom{8}{4}=70) होगा। परीक्षा में समूह शब्द दिखे तो संयोजन लगाएं।
