I have a the link below to show the Bracket I was given(the teams are different, that should not make a difference) There is 16 teams on the Sheet i was given, with what it looks like if the brackets are correct, 13 games. I need to find 2 answers

1). How many possible wasy are there for how the entire NBA playoffs could play out?

2). How many possible ways are there for how the entire NBA plays could play out WITH the ATLANTA HAWKS winning?

I believe this is a permutation but i do not know how to find the answers please help.

    I'm pretty sure the (practical) answer to the second question is ZERO.2012-10-15

There should be $15$ matches, not $13.$ Hint: Each match has $2$ possible results. If the Hawks win, how many of the matches are determined. How many are left?

    @John: That is right. The four games that the Hawks win now have only one choice, so it would be $2^{11}\cdot 1^4$, but the $1^4$ doesn't change anything. You accounted for those four games with your $15-4=11$2012-10-15
