There are 100 balls of the same shape and same weight in one bag. The balls' colors are different: 15 red balls, 25 yellow balls, 40 blue balls and 20 white balls. You are blindfolded and asked to draw three balls from the bag without replacement. Calculate the probability that there is exactly one white ball among the three balls.
