A drawer contains 12 loose red socks and 12 loose blue socks. You are completely blindfolded. What is the minimum number of socks you must pull out to guarantee you have a matching pair?
Answer: d
The worst-case scenario is drawing two different colored socks (1 red, 1 blue) on your first two pulls. The third sock drawn must be either red or blue, instantly creating a matching pair with one of the first two.
