Extracted text: 3) 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 b) Assign a value w of W to each sample points. c) 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.
