Answer:
C
Step-by-step explanation:
C
1- the answer is 1/32
each time we flip a coin the whole probabilities are 2
if we flip it 5 times
2*2*2*2*2=32
For the<span> geometric sequence, it has two forms of formula
</span>
<span>We are interested in the recursive formula now
</span>
<span>
{-80, 20, -5, ...}
The common ratio is (20/-80)=(-5/20)=-1/4=-0.25
So our r</span><span>ecursive formula would be

</span>
I hope that
helps!
I think that the answer is 120 cubes
(3/20)^3
27/8000
