问题的提出：编程模拟抛硬币所得正面的频率图。假设每次抛10次为一事件，

记录每次得到正面的次数，共抛掷100000次，计算得到正面次数的概率发布，并绘图输出结果。

思路：数值概率算法常用于数值问题的求解，此类算法所得的往往是近似解，且近似解的精度

随计算时间的增加而不断提高，得到一定精度近似解就可以满足问题要求。-Of the problem: programming simulated coin flip from a positive frequency map. Assuming a 10 per throw event, recording the number of times each receive a positive, throwing a total of 100,000 times, the calculated probability of a positive number of issued and graphics output. Ideas: Probability values commonly used in solving numerical problems, such algorithms are often derived from the approximate solution and the approximate solution accuracy with the increase of computing time rising to a certain precision approximate solution to meet the problem requirements.
