There are two boys: one marked a and one marked b. each box contains either $1 million or a deadly snake that will kill you instantly. you must open one box. one box a there is a sign that reads: "at least one of these boxes contains $1 million." on box b there is a sign that reads: "a deadly snake that will kill you instantly is in box a." you are told that either both signs are true of both are false. which box do you open? be careful! the wrong answer is fatal!

Hello.

The box to open would be: B

Because we've shown that the two statements are both true, we now know that box A has a deadly snake in it (due to the statement on box B). So the box to open is box B since this is the only box with 1 million dollars in it.

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.

Have a nice day
