[2] A fair coin to be tossed until a tail appears twice in a row. Write down the sample space S for this experiment. Let us define a random variable X as the number of tosses in the experiment. Find P(X = 4) =?, P(X = 5) =? (Hint: The sample space for this experiment consists of infinitely many elements but it is enough to write down several elements of S to show that you understood the structure of the sample space.)
