An electronic scale at an automated filling operation stops the manufacturing line after three underweight packages are detected. Suppose that the probabilty of an underweight package is 0.02 and fills are independent: a.) Find the probability that at least 100 fills can be completed before the manufacturing line is stopped.  b.) Calculate the variance and mean of x.  c.) Determine the probability mass function of the number of fills (x) before the manufacturing line is stopped.
