Heather is the general manager for a business. One of Heather's tasks is to assign extra projects to her employees. These extra projects are supposed to be assigned following a particular order. The extra projects result in additional pay, so the employees are concerned that the extra projects are assigned following the proper procedure. Errors do happen though. Heather makes an error once every 78 tasks that she assigns.
