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。
今天针对新版gre数学复习,小编给大家整理的是关于AT least One的相关内容,这些概念在考试中一定会考到的。希望考生能再接再厉,取得一个好成绩,突破新版gre数学难的困境。
AT least One
If probability of event A happening is p and event B happening is q, then the probability that at least one of them happens is .
Example:
There are 20 quarters, 33 nickels, and 47 pennies in a jar. The probability that a randomly selected coin is a quarter= 20/=20/100=0.2 and the coin is nickel = 33/100 =0.33.The probability it is either a quarter or a nickel = 0.2+0.33=0.53.
Remember:
The events needs to be mutually exclusive, that is if one happens the other cannot happen: a coin is either a quarter or nickel but not both.
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。
