高考中的线性规划题,已不再是课本中的常规题型一统天下了,而出现了许许多多的以其它知识为背景的题型,为此我们以近年各地高考题为例说明,供同学们学习时参考.1与概率同行例1(2012年高考北京理2)设不等式组0≤x≤20≤y≤{2表示的平面区域为D,在区域D内随机取一个点,则此点到坐标原点的距离大于2的概率
The college entrance examination in the linear programming questions, is no longer the text in the conventional questions dominate the world, and there have been many problems with other knowledge as the background, for which we take the college entrance examination in recent years as an example for the Students learn reference 1 and probabilistic peer Example 1 (2012 college entrance examination Beijing Li 2) set of inequality group 0 ≤ x ≤ 20 ≤ y ≤ {2 plane area is D, in the area D to take a random point, then This point to the coordinates of the origin of the distance greater than 2 probability
