Let the outcome of this experiment be the sequence of heads (H) and tails (T) resulting from the three tosses. (a) Enumerate all of the possible outcomes of this experiment. Listing the possible combinations of the two sides: HHH HHT HTH HTT THH THT TTH TTT This yields eight possiblities also revealed as 2 =8 (b) What is the probability of the outcome "HHT"? Based on (a): 1/8 (c) What is the probability of the event "The first two tosses resulted in heads"? 3 This would be 2/8 or 1/4 for the same reason as (b), i.e. HHH and HHT. (d) What is the probability of the event "There were two heads in a row among the three tosses"? This would be 3/8 for the same reason as (b), i.e. HHH, HHT, and THH.
