Solution: (I) m = {(-2,-1), (-2, 1), (0,-1), (0, 1), (2,-1).

(ii) Note that "the point with (x, y) as the coordinate is located in area D" as event a. 。

There are 6 elements in the set M, that is, the total number of basic events is 6, and the region D contains 4 elements in the set M,

So P(A)= 1

Therefore, the probability that a point with the coordinate of (x, y) is located in the region D is
