　　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-(1-p)∧n. 　　Example: 　　To understand the equation follow these steps: 　　1.The probability of the event not happening is 1-p. 　　2.The probability it won&apost happen n-times in a row is (1-p)∧n. 　　3.Probability it will happen at least once is 1-(1-p)∧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-(1-1/6)∧3=1-(5/6)∧3. 　　Remember: 　　It is much harder to directly calculate the at-least-once probability. 　　以上就是新GRE数学考点及GRE数学考点解析的介绍，希望这些知识点的介绍可以帮助大家复习新GRE数学，为大家复习新GRE数学提供条件。希望考生们认真复习新GRE数学考试，能够取得自己理想的成绩。澳际也会不断的为大家分享更多有助于考生们复习考试的新GRE考试材料及技巧。
