This maths riddle may seem simple but it has been driving the internet wild! only 2% of people can solve it within 3 minutes, can you?
Riddle:
You have 3 boxes. One of them contains a prize. You were allowed to pick just one of them.
You pick – and it’s empty.
With 2 boxes left, you now have one box in your hand and another box in front of you. If given the chance to exchange your box with the box in front of you, would you do it? Why, and why not?
(The ‘Google Riddles’ are interview questions those who wish to get hired were asked).
In the beginning, with 3 boxes, things were simple. You had a chance of 1 in 3 to find the prize. NOW we know that one of the boxes is empty but you still made a guess of 1 in 3, now you have a new choice of 1 in 2. Your probability goes up and that is why you SHOULD CHANGE THE BOX. Don’t feel bad if you disagree, this riddle has been hotly debated.

Let’s think of the three boxes as A, B and C.
Say we choose box A.
There is a 1 in 3 chance that our box has the prize inside, and so a 2 in 3 chance that it does not.
When a box is opened and shown to be empty, this DOES NOT leave us with a 50/50 chance of choosing the prize box when given the choice of switching.
We started with a 2 in 3 chance of having not chosen correctly, and so we have a 2 in 3 chance of the switch being a good choice, as it will take us to the box with the prize, since that is the only remaining box. This means that the best choice is to switch our box.
