# What is probability to get 3 balls which are red, blue and yellow?

3 colors of balls, blue,red and yellow, there are a large number of each color of balls which are distributed evenly. Ask what's the probability to get 3 balls which are all red color? What is probability to get 3 balls which are red, blue and yellow? Thanks

Large number means that large that it (relatively almost) doesn't decrease when you substract one? –  Rasmus Feb 15 '11 at 17:34
@Andy Leman: A tag (homework) would seem mandatory here. –  Did Feb 15 '11 at 17:47
@Andy Leman: OK. Interview question before what? –  Did Feb 15 '11 at 18:21
@Andy Leman: Shhh... Why get so emotional? :-) Bye. –  Did Feb 15 '11 at 18:38
@Didier This particular user doesn't seem to be in the habit of asking well-formed questions, see, e.g., his Stack Overflow profile: stackoverflow.com/users/435645/… ...48 questions, 6 above +2 votes, 0 answers. For what it's worth, even if it wasn't a homework question, I thought he treated you quite rudely. –  Uticensis Feb 15 '11 at 20:38
