A factory has two machines A and B . Past record shows that machine A produced 60% of the item of output and machine b produced 40% of the items. Further, 2% of the items produce by machine A and 1% produced by machine B wer efective. All the items are put into one stockpile and then one item is chosen at random from this and is found to be defective .What is the provability that it was produced by machine B ?
