Correct Answer
B. (462)
Concept
The captain is excluded and the vice-captain is fixed. The remaining (5) players are chosen from (11), so \(\binom{11}{5}=462\).
Why this answer is correct
The correct answer is B. (462). The captain is excluded and the vice-captain is fixed. The remaining (5) players are chosen from (11), so \(\binom{11}{5}=462\).
Exam Tip
कप्तान हट गया और उपकप्तान तय है। बाकी (5) खिलाड़ी (11) में से चुने जाएंगे इसलिए \(\binom{11}{5}=462\) है।
