Triscia had 12 jellybeans in a jar (orange ones, green ones, and purple ones). After she ate all the orange ones (but none of any other color), the probability of taking out a green jellybean by chance was twice as high as it was before she ate any jellybeans. How many orange jellybeans were there to start with, if 4 of her jellybeans were purple?

Answer 1

12/2=6 6/2=3

So the answer is 6
