The Monty Hall problem – the answer
Another day, another solution to a puzzle that I never got around to answering. Here is the puzzle again:
The Monty Hall problem is a famous puzzle based on an American TV game show. Please read the following problem and answer the poll based upon what you think you should do.
“You are a contestant on a game show. To decide your prize, you are asked to choose one of three doors (door 1, 2 or 3). Behind one of the doors is a car (good prize). Behind two of the doors is a goat (bad prize).
You choose door 3. The game show host, who knows what is behind each door, opens door 1 to reveal a goat. He then gives you the option to change your original selection to door 2.”
Is it better to stick with door 3, change your selection to door 2 or does it not matter?
The answer is below
Jousting tournament – the answer
Today, I will give the answer to a puzzle I posted a long time ago. Firstly, here is the puzzle again:
During a jousting tournament, a father and his son both compete against each other. The father is hit by a lance and dies on the spot. The son is also hit, but survives and is carried into a tent. The doctor in the tent leans over him and says “It’s my son!”.
How can this be correct?

Is seeing believing?
There is a common phrase here… “seeing is believing”. This phrase means that you are only able to believe or trust something when you have seen it with your own eyes. This, in turn, implies that when we see something, we should be able to believe it.
The following video shows one of the most amazing optical illusions I have ever seen. It’s taken from a BBC documentary called ‘Horizon: Is Seeing Believing?’ broadcast about a year ago. It shows that even our own sight is not infallible and that we should not always trust what we see.
The missing man and the missing square – the answer
There are a few puzzles hiding away in the depths of this blog that I havn’t ever got round to providing the answers for. Today I will provide the answer to two of my favourite puzzles, the missing man and the missing square. Firstly, here are the puzzles again
In the missing man puzzle, count how many men there are in the animated image. There should be 12. When the top halves of the men switch, count again. There should now be 13. Where does the extra man come from and where does he go?
In the missing square puzzle, when a series of shapes is rearranged, 1 square is missing. How is this possible?
