The average American spends about 10 minutes per week matching socks, totaling to around 8 hours per year.
On average, a person loses about 1.3 socks per month, which adds up to roughly 15 socks per year. Over a lifetime, this could amount to around 1,200 socks. However, this number can vary depending on individual habits and circumstances.
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").
