1. The possibility that the value of Stock A will increase is 0.34 and the possibility that stock B will increase is 0.68. What is the biggest possibility that neither will happen? (I am not sure about the numbers.)
I am not very sure if I was correct for this question, therefore I prefer not to mislead you. However, the answer is absolutely not (1-0.34)*(1-0.68).
我的答案:1-0。34*0。68作者: zhouxh 时间: 2002-6-6 11:39
