odd 可以当形容词，意意思是： 奇数的；古怪的；剩余的；临时的；零散的；也可当名词，意思是：奇数；怪人；奇特的事物• 如：Although it sounded odd, this is the only way to describe this behavior.虽然听起来很奇怪，但是这是描述这一行为的唯一方法。• It's not as though, oh, today is odd but maybe tomorrow it will be even.并不是说，哦，今天它是奇数,也许明天就是偶数了。而odds 只能当名词，意思是： 几率；胜算；不平等；差别 • 如：Sure, you can raise money but the odds of getting venture capital are high.当然了，你可以筹集资金，但是风险投资的几率也是非常高的。at odds是争执、不一致的意思，你应该把它作为一个整体，即一个短语来熟悉和运用，而不要去纠缠短语中某一个单词在短语中的意思。如look after，是“照顾，照看”之意，如果硬要把短语中的两个词分开理解，想望文生义，那是学不好英语的。欢迎提问，乐意解答；愿你满意, 望你采纳。

在平时probability和odds通常是可以互换的，但是在数学角度上来看两者是有一定区别的。Probability表示的是一个事件发生的几率，从0到1，如投掷一枚硬币，正面的几率为50%，反面的几率为50%。若是用odds来表示，就是1:1了。Probability is defined as the fraction of desired outcomes in the context of every possible outcome with a value between 0 and 1, where 0 would be an impossible event and 1 would represent an inevitable event. Probabilities are usually given as percentages. [ie. 50% probability that a coin will land on HEADS.] Odds can have any value from zero to infinity and they represent a ratio of desired outcomes versus the field. Odds are a ratio, and can be given in two different ways: ‘odds in favor’ and ‘odds against’. ‘Odds in favor’ are odds describing the if an event will occur, while ‘odds against’ will describe if an event will not occur. If you are familiar with gambling, ‘odds against’ are what Vegas gives as odds. More on that later. For the coin flip odds in favor of a HEADS outcome is 1:1, not 50%.
