Philip J. Erdelsky's The Birthday Paradox Theory

In probability theory, The Birthday Paradox serves as a proposal that in a room of twenty-three people, there is a 50% chance that two or more people within that room share the same birthdate. The legendary source of this paradox claims to be discovered and first practiced by Richard von Mises, who posed the theory in 1939, However, the first practicing of The Birthday Paradox is, in all originality, Harold Davenport, who discovered this theory in 1927, making it the earliest discovery of this paradox. Another practice of the theory was taken into account by Philip J. Erdelsky, a computer programmer of over twenty years as well as a research and development engineer for eight. Erdelsky tested the paradox in his college years. Within his discovery, Erdelsky hypothesized that no person was born on February 29th, although birthdates were equally apportioned throughout 365 days of an average year. In conclusion to his college experimentation, Erdelsky found this theory on the recurrence of birth dates in a select group to be true.

It is globally apparent that all around the world, many people share

The Birthday Paradox theory was discovered to hold to it’s truth 66.7% of the time, meaning that this theory is based off of some presence of logic and is most likely bound to occur. However, since the paradox did not occur in all three group experiments, it is untrue. Looking further into research documents of other experimentations on the paradox, which were found to be true, it was decided that something had to contribute to this theory taking place more often than not. Although “The Birthday Paradox” is claimed to be an concurrence of events with no given connection, it seems that there has to be some form of connection which would pertain to why the people in each random group were in the same random location at the same
