Example: A manufacturing firm is engaged in the production of steel pipes in its three plants with a daily production of 1000, 1500and 2500 units respectively. According to the past experience, it is known that the fractions of defective pipes produced by the three plants are respectively 0.04, 0.09 and 0.07.If a pipe is selected from a day's total production and found to be defective, find out a) What is the probability of the defective pipes) What is the probability that it has come from the second plant?
