Answer:
165 ways
Step-by-step explanation:
[tex] \binom{n}{m} [/tex]
That notation is read "n choose m", and it indicates the number of ways one can choose m objects from a collection of n objects, if we don't care about "order".
So in your case we have
[tex] \binom{11}{3} [/tex]
which in terms of a "factorial" notation is
11! / 3! × (11-3)!
11×10×9×8! / 3! × 8!
990 / 3
165
I've just assumed that you know what factorial means. If you don't, feel free to ask me.
