... birthday problem.


There's a famous probability exercise called the birthday problem. It's an interesting problem for sure, but typically it is calculating the wrong thing. In this series of videos we'll explore what this means.


Notes

Here's the code that we're running in the notebook.

import numpy as np
import matplotlib.pylab as plt

def calculate(room = 20):
    return 1 - np.prod((365 - np.arange(room))/365)

plt.plot([calculate(r) for r in range(1, 35)], label="calculated")
