I have never had a very good relationship with Mathematics. Math, as it turns out, is out of its bloody mind. This phenomenon is known as the Birthday Paradox. This means that with only sixty people in a room, even though there are possible birthdays, it is almost certain that two people have a birthday on the same day.

I find the amount of factors to take into account quite vast up to a point, gender and age, availability, probabilities of separation in our region, etc.
Is it even possible to calculate the probabilities on something like this? How would you go about it?
