Consider an experiment in which someone flips a fair coin. If the coin lands heads-up, then a 6-sided die is rolled and the the number that is rolled is recorded. If the coin lands tails-up, then the die is not rolled and the experiment ends. Write down the sample space for this experiment. What is the probability that a “5" is rolled during the experiment?
