In the manufacturing of a new Samsung Galaxy smartphone, there is a quality control step comprised of two tasks where a factory worker checks for cracks in in the glass front and fixes them (Task 1) and another worker applies a polish and protection solvent the glass front surface (Task 2). Task 1 must happen prior to task 2 in this process. The time it takes for each worker to perform their respect task are exponential random variables with average...
