  今天针对新GRE数学复习,小编给大家整理的是关于Geometric Figures的相关内容,希望考生能再接再厉,取得一个好的GRE考试成绩。

    Geometric Figures

  If a point is selected at random inside a geometric figure, then the probability that the selected point lies inside a particular region is the ratio of their areas:

  area of the particular region inside the figure/area of the whole figure.

    Example:

  The probability that a randomly selected point within the square lies inside the circle=area of circle/area of square=∏r2/(4r2)= ∏/4.

    Remember:

  If the particular region is not completely inside the figure, then use only the area that is inside the figure.

  俗话说:“工欲善其事必先利其器”。有一部分考生认为新GRE数学具有一定的难度,这其中的原因是由于考生在复习时没有把新gre数学的基础打牢。想要新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。
