Consider a modified version of the experiment in Example where we flip a coin until the first occurence of tails or until we flip the coin four times, whichever comes first.

(a) List the possible outcomes of this experiment. How many are there? Would you expect each outcome to be equally probable?

(b) Can you develop a method to use the classical approach to assign probabilities to this experiment?

(c) Given the probability assigment you developed in part (b), find the probabilities of each outcome listed in part (a).
