One urn contains two pieces of candy{one green and one red

One urn contains two pieces of candy{one green and one red. A second urn contains four pieces of candy{one green and three red. For each urn, each piece of candy is equally likely of being picked. You pick a piece of candy from each urn and eat the two chosen candies. If you eat exactly one piece of green candy, you draw a second piece of candy from the urn still containing a green piece of candy. You now eat the candy you just chose. What is the probability that you ate two pieces of green candy?
