If there's only 2 different kinds then you pull out 3 to get a matching pair.

The answer is 5 socks. There are only 4 different colored socks, so you could only grab a maximum of 4 socks before you would double up on colors. If you wanted to guarantee you had 2 of the same colored sock then you would need to grab 5 socks. wateva
To ensure you get at least one matching pair of socks, you would need to pick 4 socks. This is based on the worst-case scenario, where you could pick 3 socks of different colors (2 white and 1 black, or vice versa). By picking a fourth sock, you guarantee that at least one color will match, resulting in a pair.
The question is nuts - if he is in the dark, he will never know if he has a pair. If he switches the light on to check, he could pick two from the pile that matched. However if he takes 3 and walks into the light he will have a pair.
You must remove 12 socks to be sure of having a pair of Brown one

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").
just turn on the lights...
Only 5, one of each and an extra one to make a pair.
only two. each color is a completely different size. you take two of the same size
