Here is a program doing numerical calculations, which I do not see why they would not count as math: https://flatassembler.github.io/birthday_paradox

Your programme is flawed. If I enter '100' in the collisions field, the probability computes at 0%. This means that in a group of 23 people, there is no chance that they all share the same birthday. While such a coincidence is statistically unlikely, the probability is non-zero.
