A coin is tossed again and again untl a head appears or it has been tossed thrice. Write down the sample space of this experiment.

A coin is tossed until a head appears or until it has been tossed three times. Given that 'head' does not occur on the first toss, what is the probability that the coin is tossed thrice?
