55 440 different groups of 5 players.

While there is a formula for choosing so many out of so many, it is easy to work out a question like this by reasoning.

Lets' choose our 5 players one at a time....

For the first player there are 11 players to choose from:

Number of choices = #11#

For the second player, there are now 10 players to choose from.

Number of choices = #11 xx 10#

IN the same way for the third, fourth and fifth players there are 9,8 and 7 players respectively to choose from.

Number of choices = #11 xx 10 xx 9 xx 8 xx 7#

Total number of possible teams = #55 440#
