HHH, HHT, HTH, HTT... (did you see a pattern? Just repeat that until you get all the four remaining answers)
8
3
Step-by-step explanation:
As you can see in the tree diagram, there are three branches before the arrow which contains HHH and HHT. It represents how many times the coins was tossed. And as for this example, it's three times. The first branch is already filled out H and T which represents the probability at the first toss. The second branch linked in Heads is also filled out already. The second branch which is linked to Heads symbolize the possible outcomes given that the first toss produced a Head. It's just filling out all blanks with H and T and connecting the arrows altogether.
You can get the number of possible outcomes by looking at fhe the last branch in tree diagram. There, eight lines are present, which corresponds to how many possibilities are there in the event.
To know the answer in number three, you must look at your answers in number one. The number of possible outcomes will be over 8 to get it accurately. Divide both the numerator and denominator to their greatest common factor if necessary.
HTT, THT, and TTH are the only possible outcomes for this, thus having 3/8 probability.
