CodeSkulptor3 (Probability Plot) Aug 2020
I built a short presentation demonstrating the use of CodeSkulptor3 (Python 3). This time, my goal was to illustrate coding a small probability problem including a plot of results — accessible from any device — desktop, phone, iPad. Feel free to follow the links and to offer a critique. Probability of finding exactly one digit […]
