Three Door Puzzle
Step-by-step explanation:
- Probability of choosing a correct door = 1/3
- Probability of choosing an incorrect door = 2/3
Suppose we say that the door is guessed correctly which makes no difference obviously the other two doors are always wrong.
- probability of winning= 1/3 * 1 = 1
Suppose if its is guessed wrongly the other door is found to be correct.
- probability of winning = 2/3*0 = 0
- Again if suppose it is guessed correctly. By changing the guess probability of winning becomes 1/3 * 0 = 0.
- If at all the guess is incorrect. This means that the remaining door must be the correct one.
- Probability of winning is 2/3 * 1 = 2/3.
- Total chances of winning by changing the guess is 2/3 + 0 = 2/3.
