2023新gre考试实施以来，不仅对写作部分茫然不知所措，就连我们所擅长的数学也甚是担忧，相信这其中的原因还是由于考生在新gre数学复习时没有把基础打牢。如果新版gre数学基本考点都没有复习到，如何能拿到分数呢?所以说，想要新版gre数学考好，复习的时候一定要把基本概念和重要考点都弄扎实。
At Least Once
If probability of an event happening is p, then the probability that the event happens at least once in n trials is 1-n.
Example:
To understand the equation follow these steps:
1.The probability of the event not happening is 1-p.
2.The probability it wont happen n-times in a row is n.
3.Probability it will happen at least once is 1-n.
Probability that a roll of a six-sided die land with face 1 is 1/6.Then the probability that 1 will turn up at least once in 3 tries:=1-3=1-3.
Remember:
It is much harder to directly calculate the at-least-once probability.
由于美国数学基础教育的难度增加导致数学考试越来越难，但新gre数学复习考点都是高中时候学到的知识点，考生不要过于紧张，把基本概念弄明白，再记住一些新版gre数学必备的词汇，那么相信新版gre数学应该没有问题。
