The number of chips of different colors in rick's bag is shown below
3 red chips

11 green chips

7 yellow chips

rick takes out a chip from the bag randomly without looking. he replaces the chip and then takes out another chip from the bag. what is the probability that rick takes out a yellow chip in both draws?

1/9
