There are 12 volleyball players in all in a college, out of which a team of 9 players is to be formed. If the captain always remains the same, then in how many ways can the team be formed?
165
Since, It is necessarily to choose captain, 1 is already chosen.
Players left =12−1=11, More players need to choose to form a team =9−1=8
So now 11 players 8 are to be chosen.
Required number of ways = 11C8=165.
