I would like to propose a stochastic simulation tutorial that teaches using random variables generated from NumPy to simulate various situations and solve problems. The general outline for this tutorial is below.

1. Primer on generating random variables in NumPy
2. Birthday problem (https://en.wikipedia.org/wiki/Birthday_problem) – determine the probability of two students in an elementary class of 20 having the same birthday by repeatedly generating random collections of 20 birthdays and seeing how often there is a match
3. Calculate a value for pi using random numbers
4. Simulate pathogen infections using a simple SIR epidemiology model (https://en.wikipedia.org/wiki/Compartmental_models_in_epidemiology)
5. Simulate radioactive decay to determine the amount of radioactive materials left after a given amount of time
