So, what we will do is investigate both cases if I change doors and if I do not change doors. Considering all the possibilities (total number of events), we will calculate both probabilities and see which one is better. In the table below, we will assume that the car is behind door number 1 and the goats are behind doors 2 and 3 (obviously, we do not know). Then we will analyze all the possibilities, i.e., if we choose door number 1, door number 2, or door number 3, and see what happens in each case when we change doors (or do not change doors). The first column indicates our choice, while colunuis 2-4 show our choice in boldface.
