  今天針對新GRE數(shù)學(xué)復(fù)習(xí),小編給大家整理的是關(guān)于Geometric Figures的相關(guān)內(nèi)容,希望考生能再接再厲,取得一個好的GRE考試成績。

  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.

  俗話說:“工欲善其事必先利其器”。有一部分考生認(rèn)為新GRE數(shù)學(xué)具有一定的難度,這其中的原因是由于考生在復(fù)習(xí)時沒有把新gre數(shù)學(xué)的基礎(chǔ)打牢。想要新gre數(shù)學(xué)考好,復(fù)習(xí)的時候一定要把基本概念和重要考點都弄扎實。
