Each sample of water has a 10% chance of containing a particular organic pollutant. Assume that the samples are independent with regards to the presence of pollutants. Find the probability that in the next 18 samples exactly 2 contain the pollutant. (10 points)

step-by-step explanation:

answer: 0.1,0.85

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
