俗话说:工欲善其事必先利其器。很多参加了新版gre考试的同学都觉得数学有点难度,相信这其中的原因还是由于考生在新版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Multiple Times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。
新版gre数学复习重要考点:Multiple Times
If probability of an event happening is p, then the probability that the event happens n times in a row is pn.
Example:
The probability that a coin toss results in head is 0.5. Then the probability that when the coin is tossed twice, both of them are head is 0.52=0.25.
Probability that a roll of a six-sided die land with face 1 is 1/6. Then the probability that 1 will turn up three times in a row is 3.
Remember:
Note that probability of the event happening does not change from trial to trial.
