「钱永强数学难题精解」P12里面有一题:Consider an experiment with events A B and C for which P(A)=0.23 P(B)=0.4 P(C)=0.85. Also suppose that events A and B are mutually exclusive and events B and C are independent.
为什么下面能得到0.08<=P(A and C)<=0.23?完全没有头绪,为什么P(A and C)不是等于0.08?麻烦解释得详细一点。作者: shangcailanru 时间: 2013-2-8 08:08
