A test to determine whether a certain antibody is present is 99.8​% effective. This means that the test will accurately come back negative if the  antibody is not present​ (in the test​ subject) 99.8​% of the time. The  probability of a test coming back positive when the antibody is not present​ (a false​ positive) is 0.002, which is 0.2% of the time. Suppose the test is given to five randomly selected people who do NOT have the antibody. What is the probability that the test comes back negative for ALL five people? (Write your answer in decimals rounded to the nearest four decimal places, if needed)
