Consider the experiment of tossing a coin three times. how many experimental outcomes exist? let x denote the number of heads occurring on three coin tosses. show the value the random variable would have for each of the experimental outcomes. outcome value of x (head, head, tail) (tail, head, head) (tail, tail, head) (tail, head, tail) (tail, tail, tail) (head, tail, head) (head, tail, tail) (head, head, head) is this random variable discrete or continuous?
