Question
With one method of a procedure called
acceptance sampling, a sample of items is
randomly selected without replacement
and the entire batch is accepted if every
item in the sample is okay. The ABC
Electronics Company has just
manufactured 1350 write-rewrite CDs,
and 90 are defective. If 3 of these CDs are
randomly selected for testing, what is the
probability that the entire batch will be
accepted?
Rounded to four decimal place accuracy.

When doing blood testing for a viral
infection, the procedure can be made
more efficient and less expensive by
combining partial samples of different
blood specimens. If samples from three
people are combined and the mixture
tests negative, we know that all three
individual samples are negative. Find the
probability of a positive result for three
samples combined into one mixture,
assuming the probability of an individual
blood sample testing positive for the
virus is 0.08.
Round the answer to four decimal place
аccuracy.
