Simplified, it's 2 out of 3.

I assume you are selecting two socks (one at a time) from the drawer to wear (for example). There are 6 white + 3 black + 3 brown + 8 gray = 20 socks in all So the probability that the first sock chosen to be white is 6/20 since there are 6 socks and 20 socks in total. 6/20 reduces down to 3/10. The probability that the second sock chosen is also white is 5/19 since there are now only 5 white socks left to be chosen and 19 socks in total (since one sock has been taken out). Thus the probability of both socks being white is: probability = 3/10 x 5/19 = 3/38

The answer depends on where on earth the street is. In a village in much of Asia or Africa, I suggest the probability is 0.
Depends on the parents.
About 50%, if there are no other genes available.
You must remove 12 socks to be sure of having a pair of Brown one
