我有以下问题，我无法解决如何解决它。 我必须连续14次从给定的可能性中随机抽取一个数字，但在每个循环中我都有一些拒绝某些值的可能性。
我必须从以下（x）
中抽取一个值x=10:5:120;
......具有相应的概率（p）：
p=[0.0795 0.0439 0.0694 0.0259 0.1325 0.0181 0.0753 0.1885 0.0753 0.0145 0.1145 0.0229 0.0247 0.0295 0.0289 0.0066 0.0307 0.0054 0.0030 0.0036 0 0 0];
但是每次（1:14）我都有不同的概率（p2）选择一定值（b）：
b=[100 80 70 50 40 20 10]; p2=[0.9970,0.9970,0.9970,0.9822,0.9496,0.6291,0.0564;0.9970,0.9881,0.9881,0.9733,0.9080,0.5935,0.0504;0.9970,0.9970,0.9703,0.9377,0.8427,0.5460,0.0445;0.997,0.9733,0.9555,0.911,0.7478,0.4926,0.0356;0.997,0.9555,0.9377,0.8754,0.6647,0.4273,0.0326;0.997,0.9674,0.908,0.8101,0.5757,0.3561,0.0297;0.9970,0.9733,0.8843,0.7864,0.5134,0.3056,0.0267;0.997,0.9496,0.8813,0.7596,0.4777,0.273,0.0267;0.997,0.9614,0.8783,0.7478,0.4481,0.2493,0.0237;0.997,0.9674,0.8754,0.7359,0.4273,0.2255,0.0208;0.997,0.9763,0.8843,0.73,0.4095,0.2107,0.0208;0.997,0.9792,0.8724,0.7211,0.3947,0.2018,0.0208;0.997,0.9763,0.8694,0.7181,0.3858,0.1958,0.0237;0.997,0.9525,0.8694,0.7151,0.3739,0.1869,0.0267;];
举个例子：在第4次重复中，我必须从矩阵x中选择一个数字，从矩阵p给出概率，我得到0.9970概率选择一个数字低于100，0.9733选择低于80， 0.9555低于70,0.9110低于50，......等
