Answer:

52pi

Step-by-step explanation:

You need the area of the large grey circle, minus the white circle, plus the small grey

Large grey = 8^2 * pi = 64pi

White = 4^2 * pi = 16pi

Small grey = 2^2 * pi = 4pi

64pi - 16pi = 48pi, 48pi + 4pi = 52pi

Determine the probability of a negative result for a batch of size 10 if the positivity rate

Vlad1618 [11]

The probability of a negative result for a batch will be "0.3487".

Given values are:

Positivity rate,

p = 10% or, 0.1

Batch size,

n = 10

Now,

The probability of negative result will be:

→ $P (batch \ negative) = (1-p)^n$

By substituting the values, we get

→ $=(1-0.1)^{10}$

→ $= (0.9)^{10}$

→ $= 0.3487$

Thus the answer above is right.
