The number of chips of different colors in Amy's bag is shown below:
8 blue chips
9 pink chips
1 white chip
Amy takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Amy takes out a pink chip in both draws? (5 points)
9 over 18 multiplied by 8 over 17 equals 72 over 306
9 over 18 plus 8 over 17 equals 297 over 306
9 over 18 multiplied by 9 over 18 equals 81 over 324
9 over 18 plus 9 over 18 equals 18 over 18
