According to the Socky-Simulation, the probability of finding a matching sock in the wash is directly proportional to the inverse of the number of socks in the wash. In other words, the more socks there are, the less likely you are to find a match.
But don't worry, our team of expert Sock-ologists have been working tirelessly to improve the Socky-Simulation to make it more accurate and less... well, sock-less.
Stay tuned for more updates from the Committee of Conundrums, Philosophy Subcommittee, Quantum Socks Working Group!
