Question

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?

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

Answer 1

p(pink) * p(pink) with replacement so original number of chips in the bag

Answer 2

P(pink) = number of pinks out of number of chips
