X < x = x sq * PI / X sq * PI = x sq * PI / 50 sq * PI

for x = 10 it is smaller 0.04

for x = 20 it is 0.16, increases as radius increases - our chance of hitting increases

for x = 50 it is 1, does not this mean increases to max of hitting?

for x = 60 it is 60 sq / 50 sq, doesn't this mean we hit both inside (0 to 50) & possibly also outside too (50+ to 60)?... or is it definitely hit the target (as mentioned by you)?

Edit:

OK, got it, 1 is correct for x = 60, since we assumed "we definitely hit"

Mentioning "earlier assumption" as below, will help besides hinting with red color, as we are causual readers, may miss.
