# 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
