Probability theory was developed by Gerolamo Cardano, Pierre de Fermat and Blaise Pascal. In this research team, there was no cooperation at all, because they all lived at different times and were too lazy to invent the time machine. So the development of this theory lasted for centuries and is (probably) not yet finished. Cardano et al. were all committed into mental hospitals late in their lives. What are the odds against that? It is not clear whether they were actually mentally disoriented, or merely seemed to be, because of answering simple yes-and-no questions by speculating about "the chances."
