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. $(8)/(15)$ + $(7)/(14)$ = $(217)/(210)$
B. $(8)/(15)$ × $(7)/(14)$ = $(56)/(210)$
C. $(8)/(15)$ + $(8)/(15)$ = $(16)/(15)$
D. $(8)/(15)$ × $(8)/(15)$ = $(64)/(225)$

Answers

Answer 1

Answer:

Answer:

$(8)/(15) * (8)/(15)=(64)/(225)$

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 = $\frac{\text{Number of white chips }}{\text{Total no. of chips}}$

= $(8)/(15)$

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

So, Probability of getting white chip on second draw = $(8)/(15)$

Probability of getting white chip in both draws = $(8)/(15) * (8)/(15)=(64)/(225)$

Hence the probability that Gail takes out a white chip in both draws is $(8)/(15) * (8)/(15)=(64)/(225)$

Thus Option D is correct.

Answer 2

Answer: most likely the probability is D because my mom said it is d i dont know how she got it

Alana and her friends decided to have a water fight on a hot summer day. They filled a bunch of water balloons and started the fight at 12:20 P.M. The water balloons lasted for 25 minutes. When all the water balloons were gone, they sprayed water with hoses for 55 minutes, until Alana's dad showed up with ice cream. What time was it when the water fight ended?

Answers

The time was it when the water fight ended is when they started the fight at 12:20 P.M. at 1:40 P.M.

To find out what time the water fight ended, you can start with the initial time when they began the water fight (12:20 P.M.) and then add the duration of the water balloon fight and the hose spraying.

Water balloons lasted for 25 minutes, and spraying water with hoses lasted for 55 minutes, so:

Total duration = 25 minutes (water balloons) + 55 minutes (hose spraying)

= 80 minutes

Now, add these 80 minutes to the starting time:

12:20 P.M. + 80 minutes = 1:40 P.M.

So, the water fight ended at 1:40 P.M.

deepest part of a swimming pool is 12 feet deep. The shallowest part is 3 feet deep. What is the ratio of the depth of the deepest part of the pool to the depth of the shallowest part of the pool

Answers

Deepestpart of the swimming pool = 12 feet deep
Shallowest part of the swimming pool = 3 feet deep
Thus the ratio of both swimming pool depth is:
=> 12 : 3
12 – 3 = 9
The deepest part of swimming pool is 9 feet deeper compare to the shallowestpart of the swimming pool.
Ratio is simply mean the number of x is to the number of y
=> x : y

Mr. Richard's class is holding a canned food drive for charity. Juliet collected 10 more cans than Rosana. Santiago collected twice as many cans as Juliet. If they collected 130 cans altogether, how many cans did Juliet collect?

Answers

if we represent the number of cans Juliet collected as J we can express Rosanna's number as J - 10 and Santiago as 2J so all their cans together is J + 2J + J - 10=130. 4J = 140 and J = 35.
