Let W be a random variable giving the number of heads minus the number of tails in three tosses of a coin. (a) 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. (b) If the coin is fair, find the expected value of W. Explain the result intuitively.
