A manufacturing process produces integrated circuit chips, over the long run the fraction of bad chips produced by the process is around 20%. Thoroughly testing a chip to determine whether it is good or bad is rather expensive, so a cheap test is tried. All good chips will pass the cheap test, but so will 10% of the bad chips
a)Â Â Â Â Â Â Given a chip passes the cheap test, what is the probability that it is good chip?
b)Â Â Â Â Â If a company using this manufacturing process sells all chips which pass the cheap test, over the long run what percentage of chips sold will be bad?
