    Answer:

    55

    Step-by-step explanation:

    Combination will be used here as teams are a group.

    So using combination:

    No. of combination of ‘n’ things taken ‘r’ at a time

    \limits^n {C} \,_r = \frac{n!}{r! (n-r)!}

    here n = 11 ,

    r = 9

    11C9 =  \frac{11!}{9! (11-9)!} = \frac{11!}{9! (2!)}

    11C9 = 55

    Which are the possible 9 player starting lineups
