Coins are generally weighted so that when you flip one, an outcome of heads and an outcome of tails are equally likely.
(a). If you flip a coin three times, what are the possible results? One is HHH (that is, three heads
in a row). Another is HTH (heads, then tails, then heads). Write down all the possibilities.
(b). Including my examples, how many possible outcomes are there?
(c). When you flip a coin three times, what is the probability that you’ll get “tails” exactly twice?
(d). When you flip a coin three times, what is the probability that you’ll get at least one “heads”?
