8 points are spaced around at intervals of one unit around a 2 x 2 square as shown. If 2 of the 8 points are chosen at random, what is the probability that they are more than one unit apart?

For  any point chosen first, there are only   two  other points  that  are  one unit from it and five others  that  aren't....so...

 

Probability   =   5/7
