Binomial Distribution and Standard Deviation Demo

This example demonstrates the probability mass function of the binomial distribution and its approximation to the normal distribution. Core math concepts include binomial distribution, standard deviation, normal distribution, and probability & statistics. Construction highlights involve commands like BinomialDist, Normal, and objects such as n, p, mue, sigma, a, f, x_1, g, x_2, h, WP_1, WP_2, μ, Text1, Text2, Text3, Text4. Suitable for high school and above students to understand distribution properties and normal approximation.
