2. The probability that only the first ball is blue = (5/15*10/14)
The probability that only the second ball is blue = (10/15*5/14)
The probability that both balls are blue = (5/15*4/14)
=> Probability that atleast one ball is blue = (5/15*10/14) + (10/15*5/14) + (5/15*4/14)
Probability that the second ball is blue given that atleast one ball is blue = [(10/15*5/14) + (5/15*4/14)] / [(5/15*10/14) + (10/15*5/14) + (5/15*4/14)] = 0.5833
