Gce Model Questions Vol1 2018 Further Mathematics Question 10
Practice objective / multiple choice question 10 from the 2018 Gce Model Questions Vol1 Further Mathematics examination.
In a factory, machines \(A\) and \(B\) produce \(60\%\) and \(40\%\) of the output respectively. The defect rates are \(2\%\) for \(A\) and \(5\%\) for \(B\). An item is selected at random and found to be defective. The same machine then produces a second item. Before producing the second item, the machine has a \(10\%\) chance of being recalibrated, which halves its defect rate for that item only. What is the probability that the second item is also defective? Give your answer as a reduced fraction.
