A factory produces steel pipes in three plant with daily production volumes of 500,
1000 and 2000 units respectively from each of the plants. From the past experience it
is known that the fraction of defective outputs produced by three plants are
respectively 0.005, 0.008 and 0.010. If a pipe is selected at random from a day’s total
production and founded to be defective, from which plant is that likely to
have came?

Make a study about how many sheets of paper you consumed weekly in
answering your Self Learning Modules. Record the quantity (total number of sheets)
per subject, then construct a probability distribution. Compute the mean, variance,
and the standard deviation of the probability distribution you made. Interpret the
result, then find out how many weeks you will consume 50 sheets of pad paper
