The probability of a negative result for a batch will be "0.3487".
Given values are:
Positivity rate,
Batch size,
Now,
The probability of negative result will be:
→ ![P (batch \ negative) = (1-p)^n](https://tex.z-dn.net/?f=P%20%28batch%20%5C%20negative%29%20%3D%20%281-p%29%5En)
By substituting the values, we get
→ ![=(1-0.1)^{10}](https://tex.z-dn.net/?f=%3D%281-0.1%29%5E%7B10%7D)
→ ![= (0.9)^{10}](https://tex.z-dn.net/?f=%3D%20%280.9%29%5E%7B10%7D)
→ ![= 0.3487](https://tex.z-dn.net/?f=%3D%200.3487)
Thus the answer above is right.

Answer:
I think b because it goes from most to least sorry if u can't understand
4 x 5/7 = 20/7
20/7 = 2 6/7
Car A travels 180miles in 7 hours
Car A travels 25.7 miles an hour because 180/7 = 25.7
Car B travels 350 miles in 4 hours
Car B travels 87.5 miles an hour because 350/4= 87.5
Car C travels 584 miles in 15 hours
Car C travels 38.9 miles an hour because 584/9 = 38.9
Car B has the fastest average speed
