Choose two.” — expression of a universal sentiment: quality and precision are expensive and take time. This is the third and final part of the series on the birthday problem: What’s the probability that two students in a classroom share a common birthday? After mostly failing in part 1, we reached approximate answers in part 2. In this part, we will find the true pattern of the probability, translate it into code for precise calculations, and look back on the series through the prism of project management.
