2. A coin is tossed continually until a tail appears, at which point the experiment stops. Let $$A_n$$ denote the event that $$n$$ tosses are necessary to complete the experiment. (a) What is the sample space of this experiment? (b) What points of the sample space are contained in $$A_n$$ ? (c) What is $${\left(\underset{n=1}{\overset{?}{?}}{A}_n\right)}^C$$ ?
