几何概型在实际生活中的应用比较广泛,我们不妨走进三个几何概型问题来研究.一、相约会面问题例1两人相约7点到8点在某地会面,先到者等候另一人20分钟,过时离去.求两人会面的概率.分析因为两人谁也没有讲好确切的时间,故样本点由两个数(甲乙两人各自到达的时刻)组成.以7点钟作为计算时间的起点,设甲乙各在第x分钟和第y分钟到达,则样本空
Geometry in the practical application of a wide range of applications, we may wish to go into the three geometric problems to study. First, meet the same problem Example 1 Two Meet Meet 7:00 to 8:00 Meet in somewhere, first to wait One person 20 minutes out of time to seek the probability of meeting the two analysis because neither of them talked about the exact time, so the sample consists of two numbers (A and B of their respective arrival time) to 7 o’clock As a starting point for calculating time, let A and B arrive at the xth minute and the yth minute, then the sample space
