Thread: Conditional Probability Quality Control

The quality control inspector for a computer company either accepts or rejects microprocessors as a result of testing a sample of the items in a shipment. The inspector's previous performance indicates that she has:

accepted 98% and rejected 2% of all shipments that turned out to be good.
Accepted 94% of all shipments even though 5% of the shipments are known to be inferior

a) Find the probability that a good shipment is rejected
2% - i got that

b) Find the probability that an inferior shipment is accepted
The back of the book said 8%

a) 0.0120
b) 0.0788

I need to double check these!

How did you get those?
