Brain Teasers

A man was found dead in his study. He was slumped over his desk and a gun was in his hand. There was a cassette recorder on his desk. When the police entered the room and pressed the play button on the tape recorder they heard: "I can't go on. I have nothing to live for." Then there was the sound of a gunshot. How did the detective immediately know that the man had been murdered and it wasn't a suicide?

 

They police would have had to rewind the tape if the person had killed himself.

You're on a game show, and you're given the choice of three doors: Behind one door is a prize, behind the others, nothing.

 

You pick door No. 1

 

The game show host, who knows what's behind the doors, opens door No. 3, which of course has nothing behind it.

 

He then says to you, "Do you want to pick door No. 2?"

 

 

Is it to your advantage to switch your choice to door No.2?

 

Explain why or why not.

Yes.  Change.

 

The "Monty Hall Problem."

 

Changing choice has now a 2/3 probability of winning, keeping original choice 1/3.

 

Always change choice in that situation.

He knows what’s behind each door. He skipped ahead to door 3. Nothing. He knows Door 1 has the prize. Stay.

he could have done the same thing with door two and asked the peep if he wanted to switch to door 3

That's a really good one.  I'd pry choose door 2 because the host knew their was nothing behind door #3.  Unless you have a prick of a host.
