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?
大概知道它是要求條件機率，不過感覺給的條件不是很夠
大概是我的題目理解差....希望有高手人幫忙一下
給個提示也可以，給個想法也可以，感激!!
