Imagine tossing a fair coin 3 times. Give a probability model for this chance process. Sample space = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT). Each of the events has probability 1/6. Sample space = {HHH, HHT, HTH, THÍ, HTT, THT, TTH, TTT). Each of the events has probability 1/8. Sample space = {HHH, HHT, HTT, TTT). Each of the events has probability 1/4. Sample space = {3 heads, 2 heads, 1 head, 0 heads}. Sample space = {3 tails, 2, tails, 1 tail, 0 tails).
