0.028

Explanation:

Considering only the darts that reach the range target, it's reasonable to suppose that the probability is proportional to the useful area.

So, with p_T=1 corresponding to pi*6^2 ["inches"^2] (the total area of the range target), we have

p/p_T="Area of 10 points"/(pi*6^2)
p/1=(cancelpi*1^2)/(cancelpi*6^2)
p=1/36=0.02777~=0.28
