解题方法
9 . 某汽车厂商生产某型号具有自动驾驶功能的汽车,该型号汽车配备两个相互独立的自动驾驶系统(记为系统
和系统
),该型号汽车启动自动驾驶功能后,先启动这两个自动驾驶系统中的一个,若一个出现故障则自动切换到另一个系统.为了确定先启动哪一个系统,进行如下试验:每一轮对系统
和
分别进行测试试验,一轮的测试结果得出后,再安排下一轮试验.当一个系统出现故障的次数比另一个系统少2次时,就停止试验,并认为出现故障少的系统比另一个系统更稳定.为了方便描述问题,约定:对于每轮试验,若系统
不出现故障且系统
出现故障,则系统
得1分,系统
得-1分;若系统
出现故障且系统
不出现故障,则系统
得-1分,系统
得1分;若两个系统都不出现故障或都出现故障,则两个系统均得0分.系统
出现故障的概率分别记为
和
,一轮试验中系统
的得分为
分.
(1)求
的分布列;
(2)若系统
和
在试验开始时都赋予2分,
表示“系统
的累计得分为
时,最终认为系统
比系统
更稳定”的概率,则
,
,其中
.现根据
的值来决定该型号汽车启动自动驾驶功能后先启动哪个系统,若
,则先启动系统
;若
,则先启动系统
;若
,则随机启动两个系统中的一个,且先启动系统
的概率为
.
①证明:
;
②若
,由①可求得
,求该型号汽车启动自动驾驶功能后无需自动切换到另一个自动驾驶系统的概率.
