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.

Answers

Answer:

1/4

Step-by-step explanation:

8 blue chips 9 pink chips 1 white chip = 18 chips

P( pink) = pink/total = 9/18 = 1/2

Replace

8 blue chips 9 pink chips 1 white chip = 18 chips

P( pink) = pink/total = 9/18 = 1/2

P(pink, replace, pink) = 1/2 * 1/2 = 1/4

Steps:

blue chips = 8

pink chips = 9

white chips=1

total = 18

Description:

As we know that the blue chips was 8, pink chips was 9, and white chips was 1. We plus all the numbers and your answer will equal as 18. Since the pink chips are 9 and the total is 18, we put then as a fraction. So 9/18=1/2. But the answer will be 1/4

Answer: 1/4

1st draw:

pink chip = 9/18 = 1/2

2nd draw:

pink chip = 9/18 = 1/2
