Out of 14 players, let us element 2 particular player
which are excluded. Now, there are 12 players for selection of these 12, three have to be included in team always. Thus remaining players are (12 – 3) = 9 and the required players for team (10 – 3) = 7. Now,
selection cannot be done in
9C7 ways.

9C7 = 9!/7!2! = 36 ways.
