Do i have the right answers? thanks.An experiment is run.It succeeds thrice as often as it fails.Find the probability of exactly 4 successes in the experiment.The experiment has 5 trials. (Round your answer to 3 decimal places)Say you’re a chemical engineer studying whether a certain trace impurity is present in aproduct. An experiment has a probability of 0.80 of detecting the impurity if it is present. Theprobability of not detecting the impurity if it is absent is 0.90. You have reason to believe that40% of products actually contain the impurity. You perform an experiment which detected animpurity – what is the probability that the impurity is not really there?
