Answer: 380
Explanation:
Total number of players = 20
To select a captain and a vice captain :
One captain from a total of 20 players :
20 combination 1 = 20C1 = 20 ways
Total number of players left after selecting a captain = 20 - 1 = 19
Number of players left from which to select a vice captain = 19
Therefore, one vice captain from a group of 19 players :
19 combination 1 = 19C1 = 19 ways
Therefore no of different possible ways to select a captain and a vice captain :
20C1 × 19C1 = 20 × 19 = 380 Ways
