Answer:
You need to switch doors.
Switching the door has higher probability of winning.
Step-by-step explanation:
Consider the provided information.
Suppose there are 3 doors, A, B and C
Behind one door is a car that means the probability of getting a car is 1/3
Suppose you select door A
The probability that the it has a goat is 2/3. That means it is very likely to be a goat behind door A.
The other two door(B and C) are more likely to contain a goat and car.
The host opens another door which has a goat behind it. Let say he open the door B.
Now there is more chance to be a car behind it as compare to the previous choice.
Thus, you need to switch doors.
Switching the doors will gives you 2 in 3 chance of winning while staying with same door will gives you 1 in 3 chance of winning.
Switching the door has higher probability of winning.
