Hey!
-------------------------------
Let's Solve A:
1/2 = 0.5
0.5 + 0.30 = 0.80
a = 0.80
-------------------------------
Let's Solve B:
3/4 = 0.75
0.10 + 0.75 = 0.85
b = 0.85
-------------------------------
Let's Solve C:
1/3 ≈ 0.33
0.33 + 0.50 = 0.83
c = 0.83
-------------------------------
Let's Solve D:
1/3 ≈ 0.33
0.33 + 0.40 = 0.73
d = 0.73
-------------------------------
Answer:
By solving each equation we can see that option A has the lowest value!

Hope This Helped! Good Luck!
Answer:
Step-by-step explanation:
I'd tell her that if (and only if) her prediction is correct, the probability of getting tails is 0.5. Actually, the probability of getting heads would be the same, 0.5.
In real life she would not necessarily get 240 tails out of 480 tosses, but the mean value of the number of tails would indeed be close to 0.5.
Remember that finding terms in a geometric sequence is done by multiplying the previous term by a common ratio 
. For example, we can say:
We have 
. To find 
, let's multiply this term by 
:
Now, let's use this to find all of our other terms:
Thus, our terms are 64, 80, 100, 125, and (625/4).
Theres 2000 pounds in a ton. so 4000 pounds in total and she takes away 3200. 4000 - 3200 is 800. the answer is 800 pounds
