The Prisoner

A prisoner is faced with a decision where he must open one of two
doors. Behind each door is either a lady or a tiger. They may be
both tigers, both ladies or one of each.

If the prisoner opens a door to find a lady he will marry her and
if he opens a door to find a tiger he will be eaten alive.
Of course, the prisoner would prefer to be married than eaten alive.

Each of the doors has a sign bearing a statement that may be
either true or false. The statement on door one says,
"In this room there is a lady, and in the other room there is a tiger."

The statement on door two says, "In one of these rooms there is a
lady, and in one of these rooms there is a tiger."

The prisoner is informed that one of the statements is true
and one is false.

Which door should the Prisoner open?
