The odds of not getting a green card in 20 cards is actually 66.67%^20 so that's about 0.03%
I thought that originally, I guess it depends on how the cards are coloured. Like, is each one just assigned a random colour on drawing it? I assumed, perhaps incorrectly, that the cards each represent a territory and are split into 3 groups of colours, and that no card would repeat until you had went through every card. In which case, the odds are not just 2/3 each time, it actually gets slightly less with each red or blue card draw.
