Answer:
C. Yvette's independent and dependent probabilities are equal.
Step-by-step explanation:
<em>To figure this out we can use a drawing & word</em>
<em>Draw 2 marbels purple </em>
<em>Then figure out Yvette's independece & Dependece by looking at the marbels you've drawn in a notebook or scrap paper</em>
<em>Use a pencil so you erase what you put down on the paper the click the answer.</em>
Good luck Hope you get it right
remember math is math it doesn't have to be perfect as long as you keep trying. Practice makes perfect.

Given:
The geometric sequence is:

1 -4
2 20
3 -100
To find:
The explicit formula and list any restrictions to the domain.
Solution:
The explicit formula of a geometric sequence is:
...(i)
Where, a is the first term, r is the common ratio and
.
In the given sequence the first term is -4 and the second term is 20, so the common ratio is:



Putting
in (i), we get
where 
Therefore, the correct option is B.
