Answer» Each coin toss has two possible outcomes: Heads (H) and Tails (T). For k tosses, there are 2^k outcomes. Therefore, there are 2^3=8 possible outcomes when a coin is tossed three times. We can list the 8 outcomes as follows: HHH,HHT,HTH,HTT,THH,THT,TTH,TTT i) all heads = 1/8 ii) atleast two heads = HHH,HHT,HTH,THH = 4/8 = 1/2 |
