We could actually figure this out if I wanted to...
they buy like 1mil sock so about... 200k ~_~ its WRONG
Well, let's say this hypothetical person will live to be 80 years old. 80 years is about 4174 weeks. Assuming this person does laundry every 2 weeks, (their mom did their laundry for them every 2 weeks until the age of 20) that equals to 2087 washed loads in their lifetime. Assuming again, that this person loses 1 sock in the wash, on average, every third time, that equals to about 695 socks lost. Now in addition to that, this person loses socks to regular wear and tear. Let's say that they throw away an additional 5 pairs per year, because they have holes in them, or the elastic is stretched out. That would add up to 10 individual socks per year, so 800 in their lifetime. Add that to the socks lost forever to evil laundry leprechauns and you get the total of 1495. Of course each person is an individual and this number will vary greatly, but this is a pretty good estimation.
A good place to purchase matching slippers and socks would be from online retailers. Amazon offer a good range. It would be quite difficult to find matching slippers and socks on the high street.

Albert Einstein wore matching socks as a way to simplify his daily routine and save time and energy. By having multiple pairs of the same socks, he didn't have to spend time searching for a matching pair each morning, allowing him to focus on more important tasks.
There are twenty individual socks. Suppose two socks, A and B, are picked out. Consider sock A. Only one of the other nineteen socks matches it. Thus the probablility that B completes the pair is 1/19.

Pull out three socks. You will have at least one pair that matches.
In order to get a matching pair, you must take out a minimum of two and a maximum of three socks. Reasoning: The question does not specify a color for the pair of socks, it just asks for a pair of matching socks (same color). Hence, the first sock you pull will be either red or white, and the second sock you pull will also be either red or white. If the second sock matches the first one, you have a matching pair (reason for my "minimum of two"). If the second sock did not match the first sock, then you have one red and one white sock. The third sock you pull will also be either red or white and you will have a matching pair of either red or white socks (reason for my "maximum of three").

100% She will either have at least two brown socks or two white socks in any scenario.
