Exercise 5.3 An electronic scale at an automated filling operation stops the manufacturing line after three underweight packages are detected. Suppose that the probability of an underweight package is 0.01 and fills are independent. 1. Determine the probability mass function of the number of fills (X) before the manufacturing line is stopped. 2. Find the probability that at least 100 fills can be completed before the manufacturing line is stopped. 3. Calculate the mean and variance of X.

This question comes from Probability and Statistics for Engineering and the Sciences 9th Ed. by Devore, Jay Can you explain what a continuity correction is and how it is calculated? Also can you explain why .5 was chosen for this particular problem? Will it always be subtracted from one end and added to the other? Thank you for your time.
