This document describes a statistics course group project on probability. The group, called Yataycılar, has 4 members studying industrial engineering at Celal Bayar University in Manisa, Turkey in 2013. The project examines a company that receives food deliveries from trucks every 20 minutes between 6-8 am, with 5% of each load deemed unsuitable due to quality issues. The project aims to determine the probability of accepting an unsuitable item within a specific period of time.
