In a bag there are 5 red balls, 6 blue balls and 7 white balls. Two balls are drawn from the bag one after other without replacement. If the first ball turns out to be of blue colour, then 4 more blue coloured balls are to be added to the bag. Find the probability that both the balls are of blue colour.
