6. The probability that an integrated circuit chip will have defective etching is 0.06, the
probability that it will have a crack defect is 0.03 and the probability that it has both
defects is 0.02.
(a) What is the probability that newly manufactured chip will have either an etching or a
crack defect?
(b) What is the probability that a newly manufactured chip will have neither defect?
