Sock took advantage of a depleted Paris ATP Masters ... If he performs at a Top-8 level, none of his 2017 points should be too difficult to defend. Even if he doesn't win another ATP Masters ...

For example, if the first sock taken is white, there will only be 4 white socks left out of the remaining 8 socks. So the probability that the second sock is white will be \(\frac{4}{8}\).
