1、古典概型与几何概型专题训练1.在集合04Mxx中随机取一个元素，恰使函数2logyx大于 1 的概率为()A1 B.14 C.12 D.34答案及解析：2.考虑一元二次方程20 xmxn，其中,m n的取值分别等于将一枚骰子连掷两次先后出现的点数,则方程有实根的概率为()A.3619 B.187 C.94 D.3617答案及解析：3.如图，大正方形的面积是34，四个全等直角三角形围成一个小正方形，直角三角形的较短边长为3，向大正方形内抛撒一枚幸运小花朵，则小花朵落在小正方形内的概率为A.117B.217C.317D.417答案及解析：3.B.因为大正方形的面积是34，所以大正方形的边长是34，

2、由直角三角形的较短边长为3，得四个全等直角三角形的直角边分别是5和3，则小正方形边长为2，面积为4.所以小花朵落在小正方形内的概率为423417P.故选B.【解题探究】本题考查几何概型的计算.几何概型的解题关键是求出两个区间的长度（面积或体积），然后再利用几何概型的概率计算公式()=AP A构成事件的区域长度（面积或体积）试验的全部结果所构成的区域长度（面积或体积）求解所以本题求小花朵落在小正方形内的概率，关键是求出小正方形的面积和大正方形的面积.4.如图所示，现有一迷失方向的小青蛙在3 处，它每跳动一次可以等可能地进入相邻的任意一格（若它在5 处，跳动一次，只能进入3 处，若在3 处，则跳动

3、一次可以等机会进入1，2，4，5 处），则它在第三次跳动后，首次进入5 处的概率是（）A316 B14 C16 D12答案及解析：5.（1）一个盒子里有6支好晶体管，4支坏晶体管，任取两次，每次取一支，每次取后不放回，已知第一支是好晶体管，则第二支也是好晶体管的概率为()A.13B.512C.59D.925答案及解析：（1）C（2）一个盒子里有6支好晶体管，4支坏晶体管，任取两次，每次取一支，每次取后不放回，则第一次和第二次取到的都是好晶体管的概率为 ()A.13B.512C.59D.925答案及解析：（2）A（3）一个盒子里有6支好晶体管，4支坏晶体管，任取两次，每次取一支，每次取后再放回，
