新版GRE数学复习重要考点：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.
以上的内容大家一定要好好掌握，在考试的时候发挥出自己应有的水平。
