Example 8.30 If a machine is set up correctly it produces 90 per cent good items; if it is incorrectly set up then it produces 10 per cent good items. Chances for a setting to be correct and incorrect are in the ratio of 7:3. After a setting is made, the first two items produced are found to be good items. What is the chance that the setting was correct?
