标题[商管] [机率]-条件机率
时间Tue Feb 2 23:16:35 2010
A judge is 65% sure that a suspect has committed a crime. During the course
of the trial a witness convinces the judge that there is an 85% chance that
the crimianl is left-handed .If 23% of the population is left-handed and
the suspect is also left-handed, with this new information, how certain
shoud the judge be of the guilt of the suspect?
大概知道它是要求条件机率,不过感觉给的条件不是很够
大概是我的题目理解差....希望有高手人帮忙一下
给个提示也可以,给个想法也可以,感激!!
