Example:A manufacturing firm is engaged in the production of steelpipes in its three plants with a daily production of 1000,1500and 2500 units respectively. According to the pastexperience, it is known that the fractions of defective pipesproduced by the three plants are respectively 0.04, 0.09 and0.07.If a pipe is selected from a day's total production andfound to be defective, find out a) What is the probability ofthe defective pipes) What is the probability that it has comefrom the second plant?

3. In testing a certain kind of truck tire over rugged terrain, it is found that 25% of the trucks fail to complete the test run without a blowout. Of the next 16 trucks tested, find the probability that a. From 3 to 6 have blowouts, exclusive; b. Fewer than 4 have blowouts; c. More than 5 have blowouts.
Car tyres come in many different brands. Even on a car, the tyres can wear out after travelling different distances, due to cornering, braking and wheel alignment. Manufacturers of car tyres are interested in the average distance in kilometres travelled by tyres, or the lifetime of tyres until they are considered un-usable and need to be replaced. At this time a tyre is considered un roadworthy

1. Power companies severely trim trees growing near their lines to avoid power failures due to falling limbs in storms. Applying a chemical to slow the growth of the trees is cheaper than trimming, but the chemical kills some of the trees. Suppose that one such chemical would kill 20% of sycamore trees. The power company tests the chemical on 250 sycamores. Consider this a SRS from the population of all sycamore trees. Calculate the probability that less than 24% of the tress in the sample are killed. (Hint: Shape, Center, Spread, Curve, Calculations, Conclusion....)
