Suppose that a computer chip company has just shipped 5,000
computer chips to a computer company. Unfortunately, 40 of
the chips are defective.
(a) Compute the probability that two randomly selected chips
are defective using conditional probability.
(b) The probability that the first randomly selected chip is
defective is 405,000=0.008=0.8%.
Compute the probability that two randomly selected chips are
defective under the assumption of independent events.
(Round to eight decimal places as needed.)
