Answer: 14%

There are 20 marbles, so there is a 3/20 chance to pick green, an a 4/20 chance to pick yellow, so there is a 7/20 chance that the first condition will be met.
Then you have the pink marbles, which have a 8/20 (because the first marble is replaced),

Simply multiply these probabilities together to get the answer,
56/400 or 14%
