A team of 11 players is to be made from 25 players.
selecting 5 batsmen from 10 in 10C5 ways.
selecting 3 all-rounders from 5 in 5C3 ways.
selecting 2 bowlers from 8 in 8C2 ways.
selecting 1 wicketkeeper from 2 in 2C1 ways.
Thus , by the multiplication principle, we get
= 10C5 8C2
5C3
2C1 ways
Applying nCr =
= 141120 ways
