Night Market Mahjong Probability and Geometry Demo

This example dynamically demonstrates probability distribution and geometric center calculation in a night market Mahjong scenario. It involves core math concepts like probability, geometric center, general quadrilaterals, 2D vectors, perimeter, and Riemann Sum. GeoGebra commands and objects such as Sequence, Element, KeepIf, Length, Intersection, Div, Translate are used in construction. Suitable for high school mathematics teaching, illustrating practical applications of probability statistics and geometric calculations.
