anonymous · Answer

The only thing that should happen is that she gets to pick 3 equal colors.

sirm3d · Answer

when you pick 12 beans, it is possible that all 8 red and all 4 green (or blue) beans. the 13th bean guarantees that each color is present.

anonymous · Answer

I honestly don't have the formula. but since you have 8 red beans, then assume that you get all 8 and you have 4 of the blue and green ones. The safest way is to get 8 red beans and 4 of either the green or blue beans..

the 13th bean that you pick will surely be a different color.
