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。-problem : Simulation Programming throwing coins from a positive frequency map. Assuming each throwing for a 10 incident, records each receive a positive number, a total of 100,000 times thrown, calculated the probability of a positive number issued, and mapping output. Thinking : numerical probability algorithm commonly used in the numerical solution of the problem, these algorithms are often the approximate solution, and the approximate solution with the precision of the calculation time increases continuously improve, a certain precision on the approximate solution of the issue to meet demand.
