🎂 Birthday Paradox Probability Grid (2D)

A 2D Canvas simulation of the birthday paradox: adjust group size, run real Monte Carlo trials with true random birthday assignment and collision detection, and watch the empirical match rate converge on the exact closed-form probability curve.

⚙ Under the hood

Adjust the group size and run real Monte Carlo trials to see randomly generated birthdays plotted on a 365-day grid, with actual matches highlighted in red. A live chart tracks the empirical match rate against the exact closed-form probability curve P = 1 - 365!/((365-n)!*365^n).
