Do you switch doors in the Monty Hall problem?
The Monty Hall problem is deciding whether you do. The correct answer is that you do want to switch. If you do not switch, you have the expected 1/3 chance of winning the car, since no matter whether you initially picked the correct door, Monty will show you a door with a goat.
How does the 3 door riddle work?

Note that this complication does not arise in the basic Monty Hall problem with only three doors. If the player selects A (again, with no loss of generality), then the host has a choice of which door to open only if the prize is in A.
What’s the probability of winning a door switch?
If one implicitly assumes that the player selects randomly with equal probability of 1 / 3 from the three other unopened doors upon considering switching, then the probability of winning is 4 / 15, indeed, as other answerers pointed out. This can be seen to be true irrespective of how the host selects which door to open.
What’s the chance of winning all of the doors?
Now, if you decide to change to one of the other three doors, you know that you’ll have a 4 5 chance of winning (meaning if you were allowed to say “I choose this group of three doors” but not specify any single one, you would win 4 out of 5 times).
