A machine which makes bolts produces 100 units every hour among which 15 bolts on the average are discovered to be defective. Quality tests are conducted by picking 5 units from the hourly production at random. The tests require that the units picked must at most include 1 defective unit. Find the probability that the production will pass the test. 88.02% O 63.57% 83.91% O 40.34%
