Here is the solution to our riddle ‘STAIRWAY TO HEAVEN’.

STAIRWAY TO HEAVEN’ is our adaption of the notoriously famous MONTY HALL PROBLEM. But, in that there is no devil; only a timid game show host. There are two goats and a car in the original problem.

The simple answer is that the man should switch. Switching would actually increase the probability of the new door by 33%, thus raising it to 66%.
The video below will give an intuitive explanation of the problem, so do watch it.

However, it must be noted that this is a case of probability, switching doesn't necessarily translate into winning. There is still a 33% chance that the door you have selected has the prize. Switching only decreases the odds of losing, not eliminate them!!
