Answer:
a) 0.6561
b) 0.2916
c) 0.3439
Step-by-step explanation:
We are given the following information:
Let us treat high level of contamination as our success.
p = P(High level of contamination) = P(success) = 0.10
n = 4
The, by binomial distribution:
a) P(No high level of contamination)
We put x = 0, in the formula.
Probability that no lab specimen contain high level of contamination is 0.6561
b) P(Exactly one high level of contamination)
We put x = 1, in the formula.
Probability that no lab specimen contain high level of contamination is 0.6561
c) P(At least one contains high level of contamination)
Probability that at least 1 lab specimen contain high level of contamination is 0.3439
We want to determine the domain of 
any function of the form
is called an "exponential function",
the only condition is that b is positive and different from 1, and a is a nonzero real number.
The domain of such functions is all real numbers.
That is for any x, the expression <span>3(2^-x) "makes sense".
