Answer:0.5996 is the probability that none contain high levels of contamination.

Step-by-step explanation:We are

given the followinginformation:We treat lab specimen containing high levels of contamination as a success.

P( lab specimen containing high levels of contamination) = 0.12

Then the number of lab specimens follows a

binomial distribution, wherewhere n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 4

We have to find the

probability that none of the lab specimen consist of high level of contamination.We have to evaluate:

0.5996 is the probability that none contain high levels of contamination.
