Hello, andyboy179!

Yes!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?

The first "branch" looks like this:

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

And every subsequent branch is exactly the same.
