three prisoners are each given a hat. The hats come in 3 colors (black, white, and red) and it is possible for multiple prisoners to have the same colored hat. Each prisoner can only see the hats of the other two prisoners, and has to guess the color of their own (they can't hear other guesses). If at least one of them guesses right, all of them are set free. If all three guess wrong, they are sentenced to death. Find a strategy for the prisoners to guarantee success.
Just take off their own hat, lol.(jk)
Or tell another prisoner what color their hat is.(If you can)
I don't know an exact solution but those are my guesses.
