    tree diagram

    hi this is my question:

    Danny has a biased coin.
    The probability that the coin lands on heads is 2/3.
    Danny throws the coin twice.
    A) Fill in the probabilities on the tree diagram. (tree diagram at bottom of page)

    on the first head it would be 2/3 and on the first tail 1/3.
    on the second heads would it still be 2/3 and 1/3 on the tails?

    Hello, andyboy179!

    Danny has a biased coin.
    The probability that the coin lands on heads is 2/3.
    Danny throws the coin twice.

    A) Fill in the probabilities on the tree diagram.

    On the first, heads would be 2/3 and tail would be 1/3.

    On the second, would heads still be 2/3 and 1/3 on the tails?
    Yes!


    The first "branch" looks like this:


    Code:
                         [H]
               2/3    *
                  *
              *
          o
              *
                  *
               1/3    *
                         [T]


    And every subsequent branch is exactly the same.
