The number of chips of different colors in gail's bag is shown below:
3 blue chips
4 pink chips
8 white chips
gail 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 gail takes out a white chip in both draws?
a.+=
b.×=
c.+=
d.×=

Step-by-step explanation:

Given : 3 blue chips

            4 pink chips

            8 white chips

To Find:  What is the probability that Gail takes out a white chip in both draws with replacement?

Solution:

Blue chips  =3

Pink chips  =4

White chips =8

Total chips = 3+4+8 =15

Now Probability of getting white chip on first draw =

                                                                                   =  

Now ,She replaces the chip and then takes out another chip from the bag.

So, Probability of getting white chip on second draw =  

Probability of getting white chip in both draws =

Hence the probability that Gail takes out a white chip in both draws is

Thus Option D is correct.
