Even though it is 1st chance, the probability to get the key to room C-3 is 1/6...let`s start from the origin. ..room to C-3 mixed with the other 5 ...the total number of keys becomes 6...and if we try to find out our desired key randomly , we will come to know that it`s 1/6 times we could find the key. ..even if chance is the 2nd or 3rd one...#prasadsakare@IITaspirant__
