1. The problem statement, all variables and given/known data Suppose that upon using a particular testing device, a defective component has a 70% chance of being found as defective, and a non-defective component has just a 10% chance of being found defective. Suppose also that within a quality control batch, the probability of a randomly selected component being defective is 12%. i)What is the probability that a component selected at random from the batch is found to test positive (i.e. tests as being defective)? ii)What is the probability that a randomly selected component is defective, given it is found to test positive? 2. Relevant equations 3. The attempt at a solution i)I said: (0.12)(0.7) +(0.88)(.1)=0.172 ii)'m having trouble wrapping my head around this one. Did I use the correct method for the first part? Also any help in the second part would be much appreciated.
