Box B because the begining says one of the boxes contains 1 mill. so obviously the writing on box A has to be true, otherwise there would be no money in either boxes. so the writing on box B is true so we know there is a snake in box A.

Since either both signs are turthful or both are lies and one says that at least one box contains a million dollars which we know is true then they both must be true. So the sign that says the snake is in box A is also telling the truth. Grab Box B.

Both cannot be false, because if A is false, both boxes have a snake, which would make B true. Therefore, if both A and B are true, we know that the snake is in box A, and so we should open B for the $1m.

B.
You know from the sign on box A that both signs are telling the truth. Therefore the sign on box B is true, which means that the money is in B

I would open box A just because the fact box b said there was a snake in there

Hmmm, vaguely reminds me of Schrodinger's Cat.
B
Because both signs are true.
A says that "at least one box contains $" that is true.
B says the snake is in box A.
If both signs must be either true or false, we already have a sign that is inherently true. Thus Both signs are true. Open B

Open box B. If At least one box... is false that means either 0 boxes has $1 mil or 2 boxes has $1mil.

Honestly, I would open Box B. I'm not saying this because everybody else said Box B, but because I have a gut feeling about it. I'm actually visualizing the money being in Box B, and also, I would go with Box B because B is the first initial of of first name, plus it is also the first letter of my Yahoo Answer Name!
