Probability with Applications in Engineering, Science, and Technology

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.
