its an ace or a king b. its a numeric spadècoin is tossed three time then write all possible outcome and find probability of getting aat least 2 heads.all headsb.

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
