A的发生概率为0.6,B发生的概率为0.5,问A,B都不发生的最大概率? 都不发生的最大就是发生的最少,就是B的0.5含在A的0.6中,所以是0。4 如果按照上题的思路,那下面这题答案就是B. 0.32 对吗? If the probability is 0.54 that Stock A will increase in value during the next month and the probability is 0.68 that Stock B will increase in value during the next month, what is the greatest possible value for the probability that neither of these two events will occur?
A. 0.22 B. 0.32 C. 0.37 D. 0.46 E. 0.63B. 0.32 C. 0.37 D. 0.46 E. 0.63
