NFL playoff probability

[JimBob2232]

Okay, take the Buffalo Bills.

Right now, they will be in the playoffs if they win their remaining 2 games, and Baltimore, Denver and Jacksonville all go 1-1 over the last 2 weeks.

Assuming each game those 3 teams play is 50/50 that they win, what is the probability the bills make the playoffs?

Just something to tweak your minds this sunday evening (since I cant figure it out). My guess is 1 in 8 or 12%, but I suspect that is incorrect.
