问题如下：
An analyst finds that the probability of stock A outperform the market is 60%. What is the odds for of the stock A underperform the market?
选项：
A.2/3
B.1/3
C.3/2
解释：
The probability of underperform = 1 – 60% =40% The odds for of underperform = 40% / 60% = 2/3
我的理解是outperform=0.6 underperform=0.4
odds for = [1-p(underperform)]/p(underperform) = 1-0.4/0.4=3/2
可以解释一下吗？
