Perhaps a better question would be, "What are the odds that our true
position is actually in the triangle?"

Try this. Look at the LOPs that form cocked hat. Now think what the
error in each LOP might be.  Perhaps plus/minus 2 tenths of a mile to
either side? Now draw lines parallel on either side of each LOP 0.2
miles away. The results will create a larger and smaller triangle than
than you started with. Anything within the larger triangle but outside
the original cocked hat is also quite possible. If I recall threads from
the past, you have a higher probability of being outside the cocked hat
than it it.

I'll try to find the thread that. Any help locating the thread would be
appreciated.
