There’s a great maths puzzle about the three way gun fight, where one of the gun-slingers, lets’ call him Posh Gammon Robot never misses, and the second one, let’s call him Grumpy Maths Bear, is 75% accurate, while the third one, let’s call him Smarmy Egg, is only 10% accurate, in fact pretty much rubbish. Who will win? Surely PGR??
But no, because Posh Robot will shoot Grumpy Bear, and take his chances with SmEgg, while Bear’s best chance is to try to take out the deadly Robot. So Egg just has to stand there and let Robot and Bear shoot each other.
But of course if they don’t shoot each other because they have decided to convince the onlookers that they are nice people, and if Egg crows too much about still being alive, there is a risk that Gammon and Grumpy will both turn on Egg and then he’s a goner.
Remind you of anything?
