Answer 2

Answer:

165 ways

Step-by-step explanation:

$\binom{n}{m}$

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

$\binom{11}{3}$

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.
