Let’s play a little game. Imagine taking 4 playing cards out of a deck. Two of them are red and the other two are black. We mix them up and place them face down on the table. I am going to ask you to turn two of the cards face up. If they are both the same (as in, if both of them are red cards or both of them are black cards) then you win. Otherwise, I win. Is that fair?
As ever, please do NOT post your answers, but do say if you think you have solved the puzzle and how long it took. Solution on Monday.
