Answer is not 1 in 2

The probability is considered as a toughest concept of mathematics to understand. As, we can't relate this concept to a real world problems. As, the probability of raining today will be lying between 0 and 1 on any day. So, the probability will be lying between the maximum and minimum value. So, if probability of raining is 0.7, it can mean that there are more chances of raining today. But, this doesn't assure anything whether it will rain today or not. This is the reason of probability being tough concept to understand at a naive man's level. Today, I am here with puzzle of this out of the world concept of mathematics. You are here supposed to use the concept of Probability only. If you don't know about probability, do not worry. Try to solve it with the help of simple logic. Just twist the words given in the puzzle and reach to the answer.
Question:
There is a bag which contains one stone of unknown colour, either black or white. Now, you add a white stone into the bag. Now, shake the bag for a few moments and then take out one stone from the bag. The stone taken out turns out to be a white stone. Now, you are supposed to answer about the chances of the remaining stone being white. You have to answer, the probability of getting the remaining stone - white. If you reach to the answer, or have any problem reaching to the answer, comment onto this post. I will be there to help you with all ways possible. All the best.
