Assignment 3(Chapter 3) To be submitted due to Dec.3 1. Each time a component is tested, the trial is a success (S) or failure (F). Suppose the component is tested repeatedly until a success occurs on three consecutive trials. Let Y denote the number of trials necessary to achieve this. List all outcomes corresponding to the five smallest possible values of Y, and state which Y value is associated with each one. 3.A mail-order computer business has six telephone lines....
