A test to determine whether a certain antibody is present is 99.6% effective. This means that the test will accurately come back negative if the antibody is not present (in the test subject) 99.6% of the time. The probability of a test coming back positive when the antibody is not present (a false positive) is 0.004. Suppose the test is given to six randomly selected people who do not have the antibody. (a) What is the probability that the test comes back negative for all six people?

Question
A test to determine whether a certain antibody is present is
probability of a test coming back positive when the antibody is not present (a false positive) is
99.6%
effective. This means that the test will accurately come back negative if the antibody is not present (in the test subject)
99.6%

six
randomly selected people who do not have the antibody.(a) What is the probability that the test comes back negative for all
six
people?(b) What is the probability that the test comes back positive for at least one of the
six
people?
