Q4) Let W be a random variable giving the number of heads minus the number of tails in three tosses of a coin. List the elements of the sample space S for the three tosses of the coin and to each sample point assign a value w of W. Find the probability distribution of the random variable W, assuming that the coin is biased so that a head is twice as likely to occur as a tail.
