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: a coin flip from positive programming analog frequency map. Assuming throw 10 times for each event, record the number of times each receive a positive, throwing a total of 100,000 times, the calculated probability of a positive number of releases, and graphics output. Ideas: Numerical probabilistic algorithms commonly used in solving numerical problems, such algorithms are often derived from the approximate solution and the accuracy of approximate solution with the increase of computing time rising to a certain precision of the approximate solution to meet the problem requirements.
