Ok, let's play with a million boxes. That's 999,999 goats and a car.

You pick a box. The chance that you have picked the car is 1 in a million.

So the chance that the car is in one of the other boxes is 999,999 in a million.

The host now opens 999,998 boxes that he knows contain a goat. So the chance that the car is in the one remaining box is 999,999 in a million.

So do you want to keep your original pick (1 in a million), or do you want to swap (999,999 in a million)? Do you like goats?
