In a cricket team, we can not choose 2 wicket keepers
so, one have to remove while selecting 11 players
now, 11 players are chosen among 13.
Number of possible arrangement will be 13C11 ( combination of 13 player taken 11 at a time )
Now, taking the removed wicket keeper in team, number of ways will be 78 ways
so, total ways = 156 ways
