    Stat/Prob help?

    Each time a component is tested, the trial is a sucess (S) or failure (F). Suppose the component is tested repeatedly until a success occurs in three consecutive trials. Let Y denote the number of trials nessecary 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.

    how do i do this/ start..

    The smallest outcome would be SSS. Y = 3.
    The second smallest outcome would be FSSS. Y = 4.
    The third smallest outcome would be SFSSS or FFSSS. Y = 5.
    etc.
