Answer:
0.5220
Step-by-step explanation:
Since the probability of contamination is 0.15, the probability of no contamination is 1 - 0.15 = 0.85
The probability that they are all contaminated will be 0.85 * 0.85 0.85 * 0.85 = 0.52200625
This is 0.5220 to four decimal

Answer:
number 3
Step-by-step explanation:
Answer:
A. Yes, the result is a binomial probability distribution.
Step-by-step explanation:
The experiment above depicts a binomial probability distribution because the 4 required conditions are met :
1.) The distribution is independent as the possible outcome of each trial is the same.
2.) There are two possible categories and the result of each trial is one of two outcomes : Yes or No
3.) The number of observation is fixed at sample size of 5500
4.) The probability of success and failure of each trial is the same for all trials in the sample.
Hence, we can conclude that the experiment depicts a binomial probability distribution.
