An industrial widget undergoes four processes P1, P2, P3 and P4 in that order, during its last stage of production. All widgets that enter the sequence at P1 are defect free and continue to be processed till the end of P4, irrespective of any defects that may occur during any of the processes. During a quality control study, it was observed that the outputs of P2, P3 and P4 were 19%, 35.2% and 38.44% defective.Q. .If P1 has a 10% defect rate and a widget is selected randomly from the output of P3, and found to be defective, then what is the probability that a defect was introduced in the widget during P1 and during P2 but not during P3?->Approach Dena mat bhoolna
