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?

Answer 1

probability of an event happening = number of ways it can happen
                                                              total number of outcomes

Given:
blue chips = 8
pink chips = 9
white chips=1
total          = 18

1st draw:
pink chip = 9/18 = 1/2

2nd draw:
pink chip = 9/18 = 1/2

Answer 2

Answer:

81/324
