Question: . . . . . . . . . . . . . . . Hi Nick First notice that there are 11 possible squares: 8 1by1's and 3 2by2's. I don't know what you've been taught about combinations but you also need to know the total number of ways to pick 4 points from 15 points; call this number N, your answer should be 11/N. N is quite large; well over 1000. Cheers,Penny
