You want to send a secret message to your friend Alex in the mail. But Sam, who you don't trust, has access to all your mail. So you put your message in a box with a lock. But you are not allowed to send a key! How can you get your message through securely?

Answer

- Send the box with the lock to Alex. 


- Alex can't open it, but can put another lock on the box. 


- Alex sends this box with the 2 locks back to you, you unlock your lock and send it back to Alex again.


- So there is just Alex's lock on the box and Alex can now open it.

Q:

Logical puzzle

At a restaurant, how could you choose one out of three desserts with equal probability with the help of a coin? What if the coin is biased and the bias is unknown?

Answer

Our solution:


Toss the coin twice.
Let TH, HT and TT correspond to the three choices.
And if you get HH, just repeat (so it takes 8/3 tosses on average).


BIASED COIN

If the coin was biased, TH and HT would occur with equal probability.
So you could assign THHT, HTTH and THTH to the three choices, with other 4-toss outcomes rejected.
Or you could assign HTT, THT and TTH to the three choices, with other 3-toss outcomes rejected.
