It is reported that 50% of all computer chips produced are defective. Inspection insures that only 5% of the chips legally marketed are defective. Unfortunately. some chips are stolen before inspection. If 1% of all chips on the market are stolen, find the probability that a given chip is stolen given that it is defective. I understand the problem, but am confused how P(D|S) is .5. Why would it not be P(D) = .5 when 50% of computer chips produced...

1. A manufacturer of processing chips knows that 2% of its chips are defective in some way. Suppose an inspector randomly selects 4 chips for an inspection. Assuming the chips are independent, what is the probability that at least one of the selected chips is defective? 2. A box contains 4 red marbles, 3 green marbles, and 2 blue marbles. One marble is removed from the box and it is not replaced. Another marble is drawn from the box. What...
