SUMMARY
The discussion focuses on calculating the probability that exactly two colors are chosen by n people from a total of C available colors. The process involves first selecting the pair of colors, which can be done in C choose 2 (C(C,2)) ways. Subsequently, the number of onto functions from a set of size n to a set of size 2 is determined, represented as bit strings of length n containing at least one 0 and one 1. The problem was ultimately resolved by the original poster.
